eturnono (perfective verb), also aturnono: to surprise, take someone aback.
“he surprised me with [his] return”
As evident from the example above, the verb eturnono can add an additional adverbial clause with min referring to the action that is the “cause” of the surprise. Note also the alternative version aturnono. While the prefix a- is usually used to derive causatives from verb roots, the prefix e- often occurs in this role as well (as in eturnono). However, when pairs of verbs derived from a common root beginning in both a- and e- exist, the verb with the e- prefix usually has a reflexive meaning. It thus appears that aturnono was a secondary derivation (by analogy with other lexical causatives), rather than the ‘original’ causative form.
