aku v 1To commit oneself to revenge, or to get back at someone. Ko du-on ogpa-agad-agad to og-aku to ogpohimatayan to songo otow, sikan ka og-aku no og-sulì to usig. If there is someone who agrees to commit himself to kill someone else, that is the one who will be brave enough to take revenge against an enemy. [This can be used in either a good sense or a bad sense as the examples that follow show. The first example actually uses two senses of aku in the same sentence.] see: tu-ud 1. 1.1To be committed to something, especially to have committed oneself to revenge. Ko du-on ogsugù, no og-aku ka dangob to ogpohimatayon no ogtuman sikandin, sikan ka og-akuon din to og-atu to usig. If there is someone who gives a command and someone else commits to kill [someone] and carries it out, that is the enemy against whom he has committed himself to take revenge. 2To be brave enough to do something; not to be afraid to do something. Ko du-on problima ku, konò a ogkasipod to og-aku no ognangon to ogpabulig a. If I have a problem, I am not afraid to ask for help. [In combination with a negative and the word for shame, it can mean not to be afraid to do something.] see: langob.
