Synonym discussion
Sense: adjective/1
All four words describe something that the mind can accept or picture, but they differ in context and strength. 'Imaginable' is almost always tied to a superlative or to 'every/any/all' — it sounds unnatural in a plain statement ('an imaginable result'). 'Conceivable' is more formal and suits logical or philosophical argument ('every conceivable angle was explored'). 'Thinkable' is less frequent and slightly more direct ('the worst thinkable outcome'), though it can sound literary. 'Possible' is the broadest of the four, covering factual likelihood rather than mental picturing. A concrete contrast: 'That was the worst possible day' (factually bad) vs. 'That was the worst imaginable day' (emotionally, in the speaker's mind, no day could be worse).

Etymology
Comes from Latin 'imaginabilis', meaning 'that can be pictured in the mind', formed from 'imaginari' ('to form a mental picture'), which in turn comes from 'imago' ('image, likeness'). The word entered English through French during the 1300s. The core meaning — 'within the range of what one can think of' — has remained stable, but over time the word became almost exclusively tied to superlatives and universal quantifiers ('every', 'all', 'any'), a pattern that was well established by the 1600s.
