Why it looks that way
Literally "heart cruel": raai is cruel, harmful. A wicked person in Thai spoils in the heart, not in the character
A word with a story stays in memory longer than one learned as a “spelling — translation” pair: memory holds on to meaning, not to a string.
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.
- คน นี้ ใจ ร้ายкхон ний чай раайThis person is mean
Nearby words: people and family
Mum, friend, child, neighbour. The first thing people ask you about, and the first thing you tell about yourself.
- เพื่อนпхиуанfriendBroader than the close "friend": a buddy, an acquaintance, a companion. The word "buddy" in Thai is the same one — the degrees of friendship are set by life, not by the dictionary
- ครอบครัวкхропкхруаfamilyBoth kh's hold together: khrop-khrua. The Thai family lives wider than the nuclear one: aunt, grandfather and cousins count as one house
- แม่мэmother; momThe same word addresses any woman older than you — a shop assistant, the owner of a stall — and it is polite. The word also lives in the kitchen line: mae khrua — "mother of the kitchen", the cook
- พ่อпхёfather; dadThe pair of "mother" with the same rule: an older man unknown to you is addressed the same way. "Dad likes tea" is pho chop chaa — and not a single extra word
- เด็กдекchildThe same syllable as in the school name of the letter "do dek". An adult will say "dek chai" for a boy and "dek ying" for a girl, but the general word is one — dek
- คน ขายкхон кхаайsellerLiterally "person sell": who does what, Thai names through khon. A woman who sells is said with the same word
- คน ซื้อкхон сыbuyer; customerLiterally "person buy" — the pair of the seller. The buyer buys; do not swap the two at translation
- คนкхонperson; humanBoth "person" and the classifier for people: saam khon — "three people". In compounds khon means "the one who does": the seller is "person sell"
- ผู้ ชายпхуу чаайmanLiterally "male person": phuu is the polite prefix "person". Its pair, phuu ying, "woman", is assembled the same way
- ผู้ หญิงпхуу йингwomanThe pair of "man", from the same parts. The polite address to a woman is built from khun, not from 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.
