Writer's Block: Words that you love and hate

What are your favorite and least favorite words? Any reasons why?

Favorites :
English - linger (After too many times of seeing Fotr it's just stuck in my head and won't go away...)
Finnish - niittynätkelmä (it's a Finnish flower, means roughly 'small hole in a meadow'.. Argh, my English has deserted me.. I just like the word is all.)
German - Lieblichen 'darling', it's a very endearing form of the word, the ending 'chen' meaning usually something that is small. I call my darling little kitty that all the time.
Japanese - ai 'love'. Just because... :heart:
 
Least favorite words :
English - strength (because I spell it wrong all the time...)
Finnish - hammaslääkäri 'dentist' (because I hate to have to go to the dentist, there are also some anglisms that have crept into Finnish that I really hate)
German - ??
Japanese - ???
