Practice: open, closed and the red signs
What you will be able to do
Read the standing signs of a Thai street on sight: tell open from closed, find the entrance, the exit and the right door, recognise the prohibition template on any red sign, and catch the small words that change what a sign is actually promising.
Sign Thai is stripped Thai: no particles, no pronoun, almost no punctuation, and a space doing the work of a full stop. Two templates carry most of a street - ห้าม plus a verb is a prohibition, and ทาง plus a verb is a way-word - and in both of them the verb at the end is the payload, so read to the last syllable before you commit.
This card is hanging on the glass door of a shop. What is it saying?
เปิด
เปิด is bpòet, open. Its opposite, ปิด (bpìt), is the same word minus the เ, and because that vowel is written before the consonant, ปิด sits visually inside เปิด - which is why skimming for ปิ tells you nothing and you must check the left edge of the word first. Pull and push are the ดึง and ผลัก plate at hand height, a different sign on the same door, and neither of them tells you anything about whether the shop is trading. Note also that this is one bare word: speech would pad it with ครับ or ค่ะ and a subject, and the sign drops all of it.
Two words with no space between them. What is going on here?
ปิดปรับปรุง
Segment it yourself: ปิด (bpìt, closed), then ปรับปรุง (bpràp-bprung, improve or renovate). Words running together with no space is normal Thai, and the second word is the useful one here, because it is what tells you the closure is temporary rather than a goodbye. A permanent closure would not name the reason as improvement work. Neither of the open readings can be right, because the first syllable is ปิด and not เปิด - the เ is simply not there on the left edge.
You are at the counter of a government office. What are the two letters with dots between the label and the figures doing?
เวลาทำการ จ.-ศ. ๐๘.๓๐-๑๖.๓๐ น.
จ.-ศ. clips จันทร์ (Monday) and ศุกร์ (Friday) to their first letters, with the วัน that speech would add dropped along with everything else. Abbreviations wear a dot here exactly as in English. Read aloud, the board is still spoken in full: wan jan thěung wan sùk. The label in front is เวลาทำการ (wee-laa tham-gaan, office hours), so nothing on this board names a person, a counter or a floor. Notice too that the numerals are Thai: commerce wants a price read at a glance and uses Arabic figures, but the state is under no such pressure and office boards, immigration included, still often use ๐ ๑ ๒ ๓ ๔ ๕ ๖ ๗ ๘ ๙. The spaces separate label, days and hours: two gaps for three units.
Which one gets you back onto the street?
You are inside a convenience store with your hands full, and from this side both glass doors look identical.
ทางออก is thaang àwk, exit. ทาง (way) plus a verb builds a direction word, and the verb is the payload, so ทางเข้า (thaang khâo) is the entrance - identical first word, opposite meaning, which is exactly why you must read to the last syllable before you push. ห้ามเข้า (hâam khâo) is no entry, a prohibition rather than a way-word, and it would stop you rather than let you out. ห้องน้ำ (hâwng náam, literally water room) is the toilet, which is a destination inside the shop.
Which part of this word is carrying the information?
ทางออก
ทาง is the shared frame, so it tells you nothing on its own: it opens the entrance sign too. ออก (àwk) is the whole of the difference. On any ทาง sign, read the last syllable before you push the door. Signs do not carry politeness at all - that is precisely what sign Thai strips - so there is no padding syllable here. And these words work perfectly well with no pictogram; convenience stores print them on bare glass. Reading the two halves as one indivisible lump is what leaves a learner walking into the entrance door, because the half that changes is the half at the end.
Small metal plate at hand height on an office door. What should you do?
ผลัก
ผลัก is phlàk, push: a two-consonant cluster read as one syllable, and the ph is an aspirated p, never an f. Its partner ดึง (deung, pull) is on the other face of the same plate, which is why you only ever see one of the pair at a time. Convenience-store doors slide, but bank, clinic and office doors do not, so this pair settles the two-second shove-or-tug hesitation. ดึง is one live syllable with no tone mark: mid tone, exactly as the rules predict.
Stencilled in red on the gate of a house. What are you being told?
ระวังสุนัขดุ
rá-wang sù-nák dù, literally beware dog fierce: the adjective ดุ follows its noun, and there is no verb to be, which is normal Thai and not an abbreviation. ระวัง is the warning word, so nothing here is an offer or an instruction about feeding - a prohibition would open with ห้าม instead. Worth noticing the register: writing picks the formal สุนัข over the spoken หมา (mǎa), a jump nearly every sign in Thailand makes, and it is one reason these signs are worth believing rather than dismissing as decoration.
Red sign on a wall you were about to leave the bike against. What must you not do?
ห้ามจอด
ห้าม (hâam) plus a verb is the prohibition template, and จอด (jàwt) is to park. Swap the verb and you have read most red signs in the country, which is why the other three are all real signs rather than inventions: ห้ามถ่ายรูป is no photographs, ห้ามเข้า is no entry, ห้ามสูบบุหรี่ is no smoking. None of those verbs is written here. When you see ห้าม, slow down, because the verb is the part worth finishing - the rest of the sign is telling you how to avoid a fine.
The space in the middle is a sentence break, and the clause after it hangs on ไม่เกิน. What does that word tell you about the figure?
ห้ามสูบบุหรี่ ฝ่าฝืนมีโทษปรับไม่เกิน 5,000 บาท
ไม่เกิน is mâi goen, not exceeding. The law sets a maximum rather than a price, so the figure is an upper limit and you will see the same word on every official penalty notice in the country. Reading it as a fixed charge, a running total or a deposit all miss that. The first half is the plain prohibition, hâam sùup bù-rìi, and the official version simply adds the penalty clause after a space - which is the sentence break, since Thai has almost no punctuation and the gap does that work. Note that this sign uses Arabic numerals with a comma while the government hours board uses Thai ones: the ministry wants this particular number legible to everyone, tourists included.
A word in small type sits between the two things you can read from across the road. What does it change?
ลดสูงสุด 50%
ลด (lót) is a reduction and สูงสุด (sǔung-sùt) is at most, so together they promise up to, not a flat cut. Only a handful of items reach the figure, and สูงสุด is typically set in type a fraction of the size of the number beside it - the size difference is by design, so read what sits just before the figure before you get excited. It is not the shop's name, it says nothing about dates or a weekend, and it does not mean the marked prices already include the reduction. Sale signs use Arabic numerals for the same reason they shrink สูงสุด: commerce wants the figure read at a glance.
A strip of paper taped up beside the till. What is it telling you?
เงินสดเท่านั้น
Three words, no spaces, so segment the run yourself: เงิน (ngoen, money) plus สด (sòt, fresh) makes cash, then เท่านั้น (thâo-nán, only), which always follows the thing it limits. So the sign restricts you to cash rather than adding a payment option. It says nothing about change or about exact money, and it gives no reason - a broken machine would be a temporary notice, whereas this strip is the standing rule. Segmenting short unspaced runs like this is the core skill signs train.
Which door is the women's?
The corridor at the back of a mall restaurant has two doors, and the words on them are not the ones you hear people say out loud.
หญิง is yǐng, women. ชาย (chaay) is men, and its upmarket inflation สุภาพบุรุษ (sù-phâap bù-rùt, gentlemen) is the same door at a higher register - the formal upgrade on the women's door is สุภาพสตรี (sù-phâap sà-dtrii). ห้องน้ำ is just toilet, the corridor sign rather than either door. Notice that the door says one word alone, with no word for room repeated on it: nobody will ever say ชาย to you, but the door does.
The first letter of this word makes no sound at all. What is it doing there?
หญิง
The ห never sounds; it is there purely to lift the tone, which is why the word is yǐng and not ying. This is the leading-ห rule you met in the tone steps, doing its ordinary job on an ordinary door. It is not a formality marker - the formal version of this word is a different word altogether, สุภาพสตรี - and it is not a loanword flag, which is the sort of thing a ๊ or ๋ tone mark suggests instead. Nor does it hold the place of a missing vowel: the vowel here is written normally.
Which word is that letter short for?
A government hours board closes its clock time with a single letter and a dot, set apart by a space of its own.
น. is short for นาฬิกา (naa-lí-gaa) and closes any clock time, the way an abbreviation dot works in English. จันทร์ (Monday) and ศุกร์ (Friday) are also abbreviated on that board, but as จ. and ศ. in the days range before the figures, not after them. สุขา (sù-khǎa) is a written-only word for toilet you will see in older government buildings and never need to say - one of the many words in Thailand that are common in writing and almost absent from speech. Read the board aloud and nothing is clipped: it is still spoken in full.
Common mistake
เปิด and ปิด differ only by the เ, and because that vowel is written before its consonant, ปิด sits visually inside เปิด. Skimming for ปิ tells you nothing. Check the left edge of the word first, every time, and never trust where the sign is hanging: staff flip and rehang those cards all day.
