An example of the type of Suda entry where a headword is not defined but grammatically categorized. Here we have the pluperfect middle indicative, third person singular, of o)/llumi. In this precise form it is unattested outside lexicography, but for a version with initial omicron rather than omega see Homer, Iliad 10.187; perhaps the form as given in the entry has been hyper-corrected at some point in time.
For this verb, see also omicron 145, omicron 188, omicron 189.
