-tĕr is used if the Adj. ends in -ns (base ending in -nt), one of the t's being dropped; as dĕcēns, base dĕcent-, becoming, dĕcen-tĕr becomingly.
The second formation is sometimes used in the case of Adjectives of the First Class; as, larg-ŭs lavish, larg-ĭtĕr or larg-ē lavishly.
(3) The Neut. Acc. Sing. is used to form the Adverbs of some Positive Adjectives; so făcĭlĭs easy, făcĭlĕ easily; dulcĭs sweet, dulcĕ sweetly (also dulcĭtĕr). Compare § 307(1).
§ 42. Degrees of Comparison.—The Comparative Adverb is the Neut. Acc. Sing. of the Comparative Adjective.

| fort-ĭtĕr bravely | fort-ĭŭs | fortissĭm-ē |
