He wants to marry my daughter.
Need to be careful here what case you put the object in. “naida” can also mean the F-word, if you put the object in partitive instead of genitive-accusative:
“Hän haluaa naida tytärtäni”, means “He wants to f* my daughter”.
See: naida - Wiktionary
- (transitive, + genitive-accusative) to marry
- (transitive, vulgar, + partitive) to have sex with somebody
