[[OIcel morphology]]
# OIcel j-insertion

Some OIcel nouns, adjectives, and verbs belong to morphological subclasses that undergo <em class="ling">j</em>-insertion,
meaning a linking <em class="ling">-j-</em> precedes all inflectional endings beginning with <em class="ling">a</em> or <em class="ling">u</em>.[^nor]
The lack of <em class="ling">-j-</em> before <em class="ling">i</em> may be viewed as the result of [[OIcel j-deletion]].
