The Quenya word írima meant 'fair' or 'beautiful', so with the masculine ending -on, the name Írimon seems to mean something like 'fair one'. The word írima itself derived from a root meaning 'desire' or 'wish', so on an alternative reading, Írimon might be taken as 'he who is wished for'. This secondary meaning may perhaps be connected to the fact that Írimon was Tar-Elendil's third child but only son, so (under the laws of succession at that time) there was no direct male heir to the royal line until Írimon was born.
