ICELANDIC LANGUAGE. Closely akin to Norwegian, Old Icelandic was spoken in Iceland and in Greenland. A volu minous literature dates from the first half of the 12th century, written in the Latin alphabet and adapted to the special require ments of this language. No traces are found of any older runic literature. The runic monuments (about 45) are almost worth less from a philological point of view. The oldest, which date from the early 13th century, are later than the oldest manuscripts in the Latin alphabet.
Two of the oldest and most essential characteristics of Ice landic as opposed to Norwegian are the more complete vowel assimilation ( fionosto, pionasto) ; and the retention of initial h before r (hreinlega, rceinlega), l and n. Other differences, some of which occur at this period, others a little later, are—in Icel., lengthening of a, o, u before l f, lg, lk, lm and 1p (as Icel. hdl f r, Norw. and oldest Icel. hal fr, half) • later still, also of a, i, a and y before ng and nk; Icel. th and ey for older 0 and ˘y (as in Icel. dcema, lieyra, Norw. and oldest Icel. d˘ma, to deem, h˘yra, to hear) ; Icel. termination of end plur. of verbs in 6 (f) or t, but Norw. often in –r (as Icel. takiJ, –t, Norw. takir, you take). At the middle of the 13th century the written language undergoes material changes. Thus in unaccented syllables i now appears for older e, and u (at first only when followed by one or more con sonants belonging to the same syllable) for o; the passive ends in –z for –sk. Other differences from Norwegian are now completely established. With the beginning of the 14th century there appear several new linguistic phenomena: a u is inserted between final r and a preceding consonant (as in rikur, mighty) ; 4 (pronounced as an open o) passes into o (the character o was not introduced till the i6th century), or before ng, nk into au (as long fioll, pronounced lasing Oil); e before ng, nk passes into ei; a little later a passes into ie, and the passive changes its termination from –z, oldest –sk, into zt (or zst) (as in kallazt, to be called). The post-classical period of Old Icelandic (1350-153o) already shows marked differences that are characteristic of Modern Icelandic; kn has, except in the northern dialects, passed into hn, as knutr, knot; as early as the 15th century we find ddl for ll and rl (as falla, pronounced faddla, to fall), ddn for nn and rn (as horn, pron. hoddn, horn), and a little later the passive ends in –st, e.g., kallast, to be called.
