pendulum: [17] A pendulum is etymologically simply something that ‘hangs’. It is a noun use of the neuter form of the Latin adjective pendulus ‘hanging’ (source of English pendulous [18]). This was a derivative of the verb pendēre ‘hang’, which has contributed a wide range of words to English, among them penchant [17], pendant [14], pendent [15], pending [17], and penthouse, and derived forms such as append [15], appendix [16], depend, impend [16], perpendicular [14], and suspend.
=> append, appendix, depend, impend, penchant, pendant, pendent, penthouse, perpendicular, suspend - pendulum (n.)
- 1660, from Modern Latin pendulum (1643), noun use of neuter of Latin adjective pendulus "hanging down," from pendere "to hang" (see pendant). The Modern Latin word is perhaps a Latinization of Italian pendolo.
