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.
