To adjust or fit something together with another person or thing as partners.
From Latin co- (together) + adjustare (to fit, adjust). The word emerged in technical and administrative contexts where multiple elements needed precise alignment, borrowing from Old French adjuster.
This word appears most in 17th-century engineering and architecture texts—imagine two craftsmen carefully adjusting a door frame together so it fits perfectly with the wall. That's coadjusting!
