different between cranny vs aperture

Etymology 1

From Middle English crany, crani (“cranny”), apparently a diminutive of *cran (+ -y), from Old French cran, cren (“notch, fissure”), a derivative of crener (“to notch, split”), from Medieval Latin cren? (“split”, verb), from Vulgar Latin *crin? (“split, break”, verb), of obscure origin.

Despite a spurious use in Pliny, connection to Latin cr?na is doubtful. Instead, probably of Germanic or Celtic origin. Compare Old High German chrinna (“notch, groove, crevice”), Alemannic German Krinne (“small crack, channel, groove”), Low German karn (“notch, groove, crevice, cranny”), Old Irish ara-chrinin (“to perish, decay”).
