你看看我，這個經常不說母語已經不習慣了 你看看我，( ) (我) 經常不說母語，(我) 已經不習慣(說)了 您誤解了 習慣 一詞 這裡的 習慣 是 動詞 get used to 之意 而非名詞 原文必承上下文 語意才會完整 這句話省略太多 所以語意不明 而我的猜測是 : 你看看我，我經常不說母語，因此，現在即使我想說，我也已經不習慣說了 其實就是 鄉音生疏 的意思 "這個" : 某些人習慣加上一些 "發語詞" 其實無異議

Look at me, not speaking mother language often and not used to say it now.

这个经常不说母语已经不习惯了. Since I haven't spoken my native lanuage very often, I am not used to it now. 总不说母语有些不习惯了。老不说母语感觉有点不习惯了。

well,I think you know the meaning of it......the meaning is clear but the sentence is little bit odd,这个is probably a misuse of the speaker due to his/her oral habit or native idiom ,Cuz 这个 can be deleted and would be much more natural if so.

Take me as an example, I am not speaking my mother tongue for long, so that I am not used to say it now.
