【Bear】 , 【suffer】 , 【endure】 , 【abide】 , 【tolerate】 , 【stand】 , 【brook】 denote to sustain something trying or painful.

【Bear】 and 【suffer】  are also synonyms in their more comprehensive denotation, to sustain whatever is imposed.

Both verbs, however, are more often used in their specific senses because of their customary reference, with 【bear】 , to things that are heavy or difficult or, with 【suffer】 , to things that are painful or injurious.

【Bear】  suggests more the power to sustain than the manner in which something is sustained.

【Suffer】 more often implies acceptance of infliction than patience or courage in bearing.

【Endure】 and 【abide】 usually refer to long-continued trials or sufferings borne without giving.

【Endure】 usually connotes stamina or firmness of mind, while 【abide】 suggests patience and submission.

【Tolerate】 and 【stand】 imply overcoming one’s own resistance to what is distasteful or antagonistic.

【Tolerate】 often connotes failure to resist through indifference or, sometimes, through a desire for peace or harmony.

【Stand】 is often used in place of 【bear】 , but distinctively it implies the ability to keep from flinching.

【Brook】 occurs chiefly in negative constructions and implies self-assertion and defiance.

The other verbs are also used commonly in negative clauses but with weakened emphasis. In such constructions  【bear】 (with the negative) commonly implies dislike, 【suffer】 rejection, 【endure】 intolerance, 【abide】 impatience,  【tolerate】 contempt, and 【stand】 repugnance.
