-alis

Etymology
From, which later dissimilated into an early version of (e.g., mīlitāris). Perhaps connected to (cf. the sense of, from this root).

Usage notes
The suffix -ālis is added (usually, but not exclusively) to a noun or numeral to form an adjective of relationship to that noun. When suffixed to an existing adjective, the effect is and to intensify the adjectival meaning, and often to narrow the semantic field. If the root word ends in or,  is generally used instead. Sometimes both forms are found; e.g., and.
