Some etymologies treat the root as an independent one, as does the "American Heritage Dictionary". Of the etymologies that do make connections with other Indo-European roots, man "the thinker" is the most traditional — that is, the word is connected with the root *' "to think" (cognate to "mind"). This etymology relies on humans describing themselves as "those who think" (see Human self-reflection). This etymology, however, is not generally accepted. A second potential etymology connects with Latin ' ("hand"), which has the same form as Sanskrit "manus".
