"I did not run recently."
Translation:Níor rith mé le déanaí.
rithim is the present. This is the past tense. If you wanted to use synthetic forms, which are still found in Munster, you could say Níor ritheas le déanaí
And yet the verb is Rith. Does "rith mé" mean something other than "rithim" just because the tense is changed?
