What does flection mean?
Flection is a noun meaning the act of bending or the state of being bent, most often applied to limbs and joints in anatomical contexts, as when a physician measures the flection of a knee or elbow. It also carries an older grammatical sense, referring to the modification of a word's ending to express case, tense, number, or person — what modern English usually calls inflection. The word derives from the Latin verb flectere, "to bend," the same root behind flexible, deflect, and reflect. Although fully legitimate, flection is today a minority spelling: dictionaries record it chiefly as a variant of flexion, which has become the preferred form in both British and American medical writing. For everyday purposes, then, flection is best understood as the bend itself — the curling of a finger around a pen or the folding of a leg at the knee — while readers encountering it should be aware that flexion is the form they will meet far more often.

Swap one letter and "flection" becomes "reflection" — a reminder that this rare spelling is really just "flexion" wearing an older Latin coat.

Etymology of flection
Flection comes from the Latin verb flectere, meaning "to bend," via its participial stem flect- combined with the noun-forming suffix -ion. It entered English in the early seventeenth century alongside related forms such as flexion, both serving to render the same Latin idea of bending. The same root gives English flexible, flexor, reflect, and deflect. Over time flexion became the dominant spelling, leaving flection as a recognized but uncommon variant, particularly in anatomical writing.
How flection is actually used
"Flection" is a comparatively rare variant; "flexion" is now the standard spelling in anatomy and general usage, while "inflection" dominates in grammar. In American English, "flection" is especially uncommon. Writers should generally prefer "flexion."
Easily confused with flection
"Reflection" means the throwing back of light, sound, or an image, or careful thought, whereas "flection" refers to bending or grammatical inflection — they differ by only one letter but are unrelated in meaning.
