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.
