"strive for," c. 1400, from Old French aspirer "aspire to; inspire; breathe, breathe on" (12c.), from Latin aspirare "to breathe upon, blow upon, to breathe," also, in transferred senses, "to be favorable to, assist; to climb up to, to endeavor to obtain, to reach to, to seek to reach; infuse," from ad- "to" (see ad-) + spirare "to breathe" (see spirit (n.)).

pentagon (n.)youdaoicibaDictYouDict
plane figure with five angles and five sides, 1560s, from Middle French pentagone or directly from Late Latin pentagonum "pentagon," from Greek pentagonon, noun use of neuter of adjective pentagonos "five-angled," from pente "five" (see five) + gonia "angle" (see -gon).

In nature, pentagonal symmetry is rare in inanimate forms. Packed soap bubbles seem to strive for it but never quite succeed, and there are no mineral crystals with true pentagonal structures. But pentagonal geometry is basic to many living things, from roses and forget-me-nots to sea urchins and starfish. [Robert Bringhurst, "The Elements of Typographic Style," 1992]
