Sources and evidence
Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.
“Bend” follows the pattern bend → bent → bent. The same inflected form serves a finite simple-past clause and a past-participle construction; surrounding grammar identifies the role. Noun uses such as “a bend” and adjective uses of “bent” are separate from the verb-form decision.
“Bleed” follows the pattern bleed → bled → bled. The same inflected form serves a finite simple-past clause and a past-participle construction; surrounding grammar identifies the role. The verb uses the same irregular form across literal blood-loss and other established verb senses; noun uses are separate.
“Breed” is irregular: breed → bred → bred. The same inflected form serves a finite simple-past clause and a past-participle construction; grammar and surrounding auxiliaries identify the role. The same irregular form applies across reproductive, cultivation, and figurative produce/engender senses, even though those senses remain semantically distinct.
“Bring” follows the pattern bring → brought → brought. The same inflected form serves a finite simple-past clause and a past-participle construction; surrounding grammar identifies the role. The reviewed standard paradigm is bring → brought → brought; avoid unsupported claims about every dialectal or nonstandard form.
“Build” follows the pattern build → built → built. The same inflected form serves a finite simple-past clause and a past-participle construction; surrounding grammar identifies the role. The ordinary irregular paradigm is build → built → built; do not infer an unreviewed regular past form.
“Catch” follows the pattern catch → caught → caught. The same inflected form serves a finite simple-past clause and a past-participle construction; surrounding grammar identifies the role. For ordinary standard uses of the verb, do not regularize the past as “catched”; the reviewed authorities give “caught” for both past roles.
