Assuming it is a word, then:

'logy' is from Ancient Greek 'logos' and means speech or reckoning; while 'na' means not ever.

http://en.wiktionary.org/wiki/na

From the above url, 'na' can also mean he/him, she/her, well!, swim!, so!, yes/is, no/not, binary question, here, direction, on, at or in among others.

Of course, you might get different results if you split the characters differently.
