==== Usage notes ====
The suffix causes gemination of the preceding single consonant if added directly to the base (e.g. ''huntar'' → ''hunta'''rr'''iaht''). The gemination does not take place if the base does not end in a single consonant (e.g. ''ewant'' → ''ewa'''nt'''iaht''), or if the base ends in a vowel (e.g. ''hranus'' → oblique ''hrani-'' → ''hraniaht''). In some cases, the initial vowel of the suffix is omitted (e.g. ''olke'' → oblique ''olke'' → ''olkeaht''), which mostly happens in heavy vowel-stems.
