What does adduct mean?
Adduct is a technical verb meaning to draw a limb or body part toward the midline of the body, or toward the midline of another part. It belongs mainly to the vocabulary of anatomy, medicine, physical therapy, and sports science: a clinician might ask a patient to adduct the hip by moving the leg across the center of the body, while an exercise description might note which muscles adduct the shoulder. Its opposite is abduct, meaning to move a limb away from the midline, and the two are frequently contrasted in medical writing. The word derives from Latin adducere, 'to lead toward', sharing its root with familiar words such as produce and reduce. In chemistry, the related noun adduct refers to a compound formed when two molecules combine directly. Though uncommon in casual speech, adduct is precise and useful wherever human movement is described scientifically.

- (Chemistry, as a noun) A new chemical species formed by the direct combination of two separate molecules without loss of atoms from either.
"The physiotherapist asked him to slowly adduct his leg against gentle resistance."
"Tightness in the chest muscles can make it difficult to fully adduct the shoulders."
"The chemists isolated a stable adduct formed between the protein and the reactive metabolite."
The plural applies only to the chemistry noun meaning a compound formed by combination of two molecules; the verb does not have a plural.
"Mass spectrometry revealed several DNA adducts formed by the carcinogen."
Every time you squeeze your arms against your sides, you're adducting — and its opposite, abducting, is what your body does every step you take.

Etymology of adduct
Adduct comes from the Latin adducere, meaning 'to lead or bring toward', formed from ad- ('toward') plus ducere ('to lead'). It entered English in the early modern period, with its anatomical use established alongside the older general sense of bringing something toward a point. It shares the ducere root with many English words, including deduce, educate, produce, and reduce, all of which carry the underlying idea of leading or drawing something.
