would /wʊd/, also /wəd/ in American English.
Spelled w, o, u, l, d. The l is silent: /w/ maps to w, /ʊ/ to o(u), /d/ to d, while the l marks nothing in speech.
I would love some tea. /aɪ wʊd lʌv səm tiː/
She would know the answer. Spoken quickly, the vowel often reduces to /wəd/ with a schwa, so the full spelling keeps the l even though it is not heard.
She said she would come. Here would stands alone, with no verb after it, and keeps /wʊd/ in careful speech; the written l is simply silent.
One caution: wood /wʊd/ sounds identical to would in careful speech, but its meaning is completely different. Spell it w-o-o-d with no l, or you have written a different word.
In wood, the vowel is /ʊ/ just as in would, and nothing but the l separates the two spellings, so the extra letter is your only written clue.
