Contractions are commonly found in English speech, and is the term for words where apostrophes are used to denote absent letters, e.g. "it's", "don't", and "you're".
However, in written English, and therefore Radiopaedia we generally prefer the non-contracted form, e.g. "cannot" instead of "can't", "we would" instead of "we'd", etc.
NB: "its" is not a contraction but the possessive form of the word "it".
English contractions
This is an alphabetical list of contractions in spoken English, followed by the non-contracted form which is what we would prefer to appear in Radiopaedia articles and cases. Occasional forms can denote two different forms and it is "usually" possible to work out from the context which one was meant.
The only exception to removing contractions is when a contraction appears in quoted speech (rare) or the title of a referenced article.
