Alpha privative
Template:Short description An alpha privative or, rarely,<ref>Ngram Viewer</ref> privative a (from Latin {{#invoke:Lang|lang}}, from Ancient Greek {{#invoke:Lang|lang}}) is the prefix a- or an- (before vowels) that is used in Indo-European languages such as Sanskrit and Greek and in words borrowed therefrom to express negation or absence, for example the English words of Greek origin atypical, anesthetic, and analgesic, as well as the English word of Sanskrit origin ahimsa (ahinsa).
It is derived from a Proto-Indo-European syllabic nasal *Template:PIE, the zero ablaut grade of the negation *Template:PIE, i.e. /n/ used as a vowel. For this reason, it usually appears as {{#invoke:Lang|lang}} before vowels (e.g. an-alphabetism, an-esthesia, an-archy).<ref name="LSJ">Template:LSJ</ref> It shares the same root with the Greek prefix {{#invoke:Lang|lang}} or {{#invoke:Lang|lang}}, in Greek {{#invoke:Lang|lang}} or {{#invoke:Lang|lang}}, that is also privative (e.g. {{#invoke:Lang|lang}}).<ref name="LSJ1">Template:LSJ</ref>
It is not to be confused with, among other things, an alpha copulative (e.g. a-delphós) or the prefix {{#invoke:Lang|lang}} (i.e. the preposition {{#invoke:Lang|lang}} with ecthlipsis or elision of its final vowel before a following vowel; e.g. {{#invoke:Lang|lang}}).
CognatesEdit
SanskritEdit
The same prefix appears in Sanskrit, also as {{#invoke:Lang|lang}} before consonants; and {{#invoke:Lang|lang}} before vowels (written अ and अन्, respectively in Devanagari).
LatinEdit
In Latin, the cognate prefix is {{#invoke:Lang|lang}}, which leaves its traces in English words like invisible and inaccessible, and in its assimilated form in words like irresistible, irrelevant, irresponsible, illegitimate, illegal, illiterate. The prepositional prefix {{#invoke:Lang|lang}} is unrelated.
Germanic languagesEdit
In English and other West Germanic languages, the cognate is un- (or on-).
In North Germanic languages, the -n- has disappeared and Old Norse has {{#invoke:Lang|lang}} (e.g. {{#invoke:Lang|lang}}), Danish and Norwegian have {{#invoke:Lang|lang}}, whereas Swedish uses {{#invoke:Lang|lang}} (pronounced [u]), and Icelandic and Faroese use the related {{#invoke:Lang|lang}}.
HomonymEdit
The prefix {{#invoke:Lang|lang}} {{#invoke:Lang|lang}} (also {{#invoke:Lang|lang}}- {{#invoke:Lang|lang}} from psilosis), copulative a, is nearly homonymous with privative {{#invoke:Lang|lang}}, but originates from Proto-Indo-European *Template:PIE.<ref name="LSJ" />
