There are only five words that use the อ sex-change doctor, all of them starting with ย.
|อยุด||stop||"dead boy" - sad tone|
|อยาก||to want (to do something)||"dead boy" - sad tone|
|อยู||to live/reside, to be at (a place); to be happening continuously (-ing)||"singing boy" - boring, no tone|
|อย่า||don't||"dagger on boy" - sad tone|
type, kind, sort, a quality of an object or person; as, like, in the way of... (changing an adjective to adverb as in -ly)
|"dagger on boy" - sad tone|
Get to know them because then for all other words spelled using อ, it can only either be:
- a silent consonant "placeholder" for any vowel that is attached to it
- the "awe" vowel if attached to the right side of any consonant.
The only time where there may be a potential ambiguity is when no vowel is written, as in:
|อก||chest||invisibe "o" vowel: "ok"|
|อบ||bake; to scent/perfume||invisibe "o" vowel: "ob"|
|อด||to go without, miss, refrain||invisible "o" vowel "od"|
|อม||hide; embezzle/cheat; suck in mouth||invisible "o" vowel: "om"|
|องค์||organ, body part||invisible "o" vowel: "ong"|
|องุ่น||grape||spacer "a" vowel: "a-ngun"|
|อโศก||Asok||spacer "a" vowel "a-soahk|
|อธิบาย||to explain||spacer "a" vowel: "a-tibaai"|
In general, except for the top five 2-letter words, which are single-syllable words, if you see อ as the first letter of a multi-syllable word and no vowel written then it is most likely to be the spacer "a" vowel.
