conbeir

Old Irish

From com- +‎ beirid.

con·beir (verbal noun compert)

The two senses ("bring/bear together" and "conceive") seem to conjugate differently in the perfect and possibly other augmented forms. For "bring together", a suppletive stem com- +‎ ro- +‎ ·uic appears; while for "conceive, beget", a non-suppletive stem com- +‎ ad- +‎ ·beir occurs instead.
