In a live sentence
A single word almost never appears alone in conversation. A sentence shows where it fits and what stands next to it.

Nearby words: verbs
I want, I can, I am going, I know. The verb holds a sentence together: a few of the most frequent ones cover more everyday talk than a long list of nouns.
- ขอкхоI want; I will takeThe main word of ordering: literally "I ask". "I want coffee" in Thai is kho kafae khrap, and that is politer than a flat "I want". It does not conjugate: I and you say the same kho
- ชอบчопto like; to love"Love" in the sense of "like" — about food, music and people. Love for a person Thai says with another word (rak), and the two cannot be mixed up
- ไปпайto goOne verb for on foot, by bus and by plane. At the end of a phrase it also means "to be off": pai kon — "I am off". It changes for neither person nor time
- กินкинto eatThe neutral "eat". Politer is than; about animals kin is used without embarrassment. The Thai greeting formula is "let's go eat rice": pai kin khao
- ดื่มдыымto drinkA long syllable with a dead end — the p is not released. About alcohol Thai speaks with the same word: duem bia — "drink beer"
- อ่านанto readThe tone falls. The book is nangsue, and "read a book" is a pair that always lives together
- พูดпхуытto speakA low-class ph with a puff of air. "To speak Thai" is assembled through "language": phut phasaa thai — literally "speak language Thai"
- ทำ งานтхам нганto workLiterally "do work": the two words always go as a pair, and the verb here is exactly "do". The same turn answers "what do you do for a living?"
- ต้องтонгmust; to have toLiterally "it is required": after it the verb goes unchanged, as in "one must go". No person shows on it either — "must" is one word for everybody
- อยู่юto live; to be located"Live", "be located" and "stay put": one word for everything where "to be somewhere" is needed. Yu thinai? is "where do you live?" and "where are you?" at once

How not to forget this word
Reading a word and remembering it are different jobs. A day later, little survives of a single reading — and that is not bad memory, that is how memory works.
- This has been tested on foreign words too. The difference shows up most when you test yourself a few days later rather than straight away.checked many timesKim & Webb, 2022, Language Learning 72(2) · 48 experiments, 3,411 participants, 98 comparisons.
