Hmm... I agree with Declan... but I would have thought Liam would be better written as: リーアム
I would do what EZ wrote (note: I lose lots of marks on katakana spelling)
Katakana doesn't look very cool though >_>
matching Kanji/Hanzi to the sounds Chinese-style would look so much cooler, although would read like gibberish.
Well... I'm going to give him a couple of links about all of this, just so he can understand a little better... one of sites reads:
"Kanji is generally not used to write foreign names. However if you wish to have a kanji name, try the following sites. Please note that although foreign names can be translated into kanji, they are translated purely on a phonetic basis and in most cases will have no recognizable meaning."
I spose I can always give him a few kanji options... I've found a few online for Liam, but Declan is a bit harder.
I dunno... I'm kind of adverse to gibberish kanji names... I hope he doesn't decide on using kanji just coz it looks cooler.
