different between could vs would

English

Alternative forms

• coud (obsolete)
• cou’d (obsolete)

Etymology

From Middle English coude, couthe, cuthe, from Old English c?þe, past indicative and past subjunctive form of cunnan (“to be able”) (compare related c?þ, whence English couth). The 'l' was added in the early 16th century by analogy with should and would; this was probably helped by the tendency for 'l' to be lost in those words (and so not written, leading to shudd, wode, etc).

Pronunciation

• (stressed) IPA^(key): /k?d/, [k??d]
• (unstressed) IPA^(key): /k?d/, [k??d]
• Rhymes: -?d

Verb

could

1. simple past tense of can

   Before I was blind, I could see very well.

Usage notes

• As an auxiliary verb, would is followed by the bare infinitive (without to):

  John said he would have fish for dinner.

• Would is frequently contracted to 'd, especially after a pronoun (as in I'd, you'd, and so on).
• The term would-be retains the senses of both desire and potentiality (those of wannabe and might-be, respectively).
• Indicating a wish, would takes a clause in the past subjunctive (irrealis) mood; this clause may or may not be introduced with that. Most commonly in modern usage, it is followed by the adverb rather, as in I would rather that he go now. A call to a deity or other higher power is sometimes interposed after would and before the subjunctive clause, as in Would to God that […] ; see the citations page for examples.
• When used, mainly archaically, in the sense of "if only", the first-person subject pronoun is often omitted.

Synonyms

• (indicating an action in the past that happened repeatedly or commonly): used to
• (used to express a polite request): be so good as to, kindly, please

Translations

Note: many languages express some meanings of would using a mood or tense rather than by a particular word.
