How do I decipher each word in a sentence, if all is written in hiragana?


I don't know what this sentence means. "相変わらずつーといえばかーだね". I tried using google
translate but it produces way too different meanings, when I try to translate
the sentence bit per bit.

ex. 相変わらずつーといえばかーだね= As usual I can not stop talking to you.  
つーといえばかーだね= It's awfully cool  
つーといえばかー= Wait a minute.

Does this mean that the original sentence means "As usual she's awfully
cool."? Is the word for word of the sentence like this; 相変わらず つー と いえ ばかー だ ね?
or is it 相変わらず つー と いえば かー だ ね?  
But the words: つー and かー do not make sense to me.




> 「相変{あいか}わらずつーといえばかーだね。」

≒

> 「相変わらず、『つーと言えばかー』だね。」

≒

> 「相変わらず、二人{ふたり}は『つーと言えばかー』の関係{かんけい}だね。」

「つーといえばかー」 is an idiomatic expression describing **what great communication
two persons have with each other**. You just have to memorize it.

I honestly do not know how you could get "cannot stop talking to you",
"awfully cool" or "wait a minute" **even if** 「つーといえばかー」 were not an idiomatic
expression.

> "As usual, (the two persons) have great communication with each other, don't
> they?"

Finally, regarding where 「つー/つう」 and 「かー/かあ」 come from, they are both
sentence-ending particles. The latter has remained till today but the former
has changed to 「とさ」.

「かあ」: Used as an exclamation when talking to oneself as in
「ここのラーメン、1,000円{えん}もするの **かあ** 。」

「とさ」: Used as a quotative or expressing hearsay as in
「その後{ご}、おじいさんは幸{しあわ}せに暮{く}らした **とさ** 。」

It is probably faster if you memorized the idiomatic expression as is without
analyzing its components.

This expression is far more common among native speakers than you might think.
There used to even exist a large cellphone company named 「ツーカー」. A nice name
for a cellphone, isn't it?
