Acronym inflection

Acronyms are inflected using a colon, followed by the inflectional endings, which depend on either last letter of the word or inflection class of the last word of the abbreviation. The exception to the inflection scheme is the singular nominative, which appears without colon. Pronouncable abbreviations such as aids, hiv, kela, alko etc. are actually counted as regular words with regular inflection patterns. c.f. VISK § 169

Acronyms ending in numbers inflect like the numbers are pronounced.
