The headword is the aorist indicative, first person singular, of the verb a)dolesxe/w , used in all periods. In the classical age it seems to have negative implications (to talk idly), but less so subsequently.
[1] Quotation excerpted from Theodoret, Interpretatio in Psalmos 80.1477b Migne, commenting on Psalm 76.4 LXX: h)dole/sxhsa, kai\ w)ligoyu/xhsen to\ pneu=ma/ mou; 'I talked, and I was discouraged in my soul'. He continues: 'conversing with myself and considering the evils constraining me I gave up [trying] to remove them, and accepted the sharp pains of my despondency'.
