Origin of sagacity
Latin sāg- and sag- come from a Proto-Indo-European root sāg- (with variants) “to track by scent, track, seek out.” Sāg- becomes hēg- (dialect hāg- ) in Greek, forming the verb hēgeîsthai (dialect hāgeîsthai ) ”to guide”; Old Irish has saigim “I search.” The Germanic development of sāg- is sōk-, from which the verb sōkjan “to seek” is formed, becoming sēcan in Old English (English seek ).
