What does 「諜づかいがオタナリ」 mean?


I came across this sentence as a bullet point on a manga character's info
sheet. I think it may be alternatively written 「諜使いがヲタナリ」 since I gather
「ヲタナリ」 means something like “otaku wannabe”, is that correct?




Turns out I misread the handwriting -- I'm pretty sure @chocolate's suggestion
of 「言葉づかいがキタナい」 is correct, meaning that the character is foul-mouthed.
