iii. Many composite nominal prepositions have no corresponding simple form (i e. the noun alone is not used as a prep.). All are followed by the [rad.]. The most important are
(1) mewn, Ml. W. y mywn, myuon * in ' (though apparently a simple form, myicn is a mere phonetic reduction of ymywn} ; o fewn ' within ' ; with inf. pron. i'w mewn hi Num. v 24 ; och meion Luc xvii 21 ; also in Mn. W. i fewn y Uys Marc xv 16 ; adv. i meicn^ oddimeicn.
(y)mywn ' in the middle of ' has come to be used for ' in ' before indefinite, yn being restricted to definite, objects ; thus ymywn ty W.M. 53 ' in a house \ yn y ty do. 54 ' in the house ' ; in Ml. and Early Mn. W. mywn, mewn is sometimes used before the latter.
i < *ens : Gk. ets < evs < *en ( in ' + -s as in *eks. i mewn, ymywn = Ir. inmedon, immedon ; Ir. medon ' middle '. The W. form has lost 8 110 iv (2), and was therefore orig. disyllabic *my\wn < *mywn, which most probably represents *my8-wyn 78 i (2). Both this and Ir. medon would be regular from Kelt. *mediokno : Lat. mediocris, spv. medioxtmus. If this equation is right, mediocris can hardly be ' *middle-hill ' (: ocris, Sommer 488, Walde s.v.) but may be an adj. in -ri- (cf. dcri-, sacri-) from *medioque formed from medio- like proj)e (for *proqiie) from pro, as the spv. medioximus beside proximu* suggests. The Kelt, would be a noun in -no- from the same (It.-Kelt.) extd. stem. Orig. stem *medh(i)io- : Skr. mddhya-h, Gk. /i(TO-S.
