NOTE: The suffixes arise from adding -lis (stem li-) to various vowel stems. The long vowels are due partly to confusion between stem and suffix (cf. vítá-lis, from vítá-, with rég-ális), partly to confusion with verb-stems: cf. Aprílis (aperíre), edúlis (edere), with senílis (senex). -ris is an inherited suffix, but in most of these formations -áris arises by differentiation for -ális in words containing an 1 (as mílit-áris).
