/rəˈtɪkjələr/

Origin: A borrowing from Latin. Etymon: Latin reticularis.

Etymology: < post-classical Latin reticularis (1532 in a British source on anatomy) < classical Latin rēticulum small meshwork bag, small net (see reticulum n.) + -āris -ar suffix¹. Compare French réticulaire (see reticulary adj.), Spanish reticular (1589), Italian reticolare (a1555).

a. Chiefly Anatomy. Resembling a net in appearance or construction, netlike; consisting of interwoven fibres, filaments, etc.; of or relating to a reticulum.
