Etymology
The word 'flexor' is a modern anatomical term constructed directly from Latin components. Its core, 'flex-', originates from the Latin verb flectere, meaning 'to bend'. This root is traceable to the Proto-Indo-European root bʰleg-, which also meant 'to bend' and is the ancestor of related English words like 'flexible'. The suffix '-or' is a Latin agent suffix, typically used to form nouns denoting an agent or instrument. Therefore, the literal construction 'flexor' logically means 'that which bends', a precise and descriptive label for a muscle whose primary function is to decrease the angle at a joint.
