Today was a pretty incredible day for America, and not just from a political standpoint. Anybody who muddled through the examples will have realized exactly who I was rooting for and why I might be tempted to assault you all with a slew of new sentences now that everything is decided. I will, however, refrain. There are dozens of sites already devoted to the subject, but only one site dedicated to providing five Japanese grammar points. Which will be about Nintendo's new handheld, the DSi!
181) ～をきっかけに ・ ～をきっかけとして（にして）
Taking advantage of ~, ...
Since ~, I figured ....
Since ~, I may as well ...
Another one that's kind of tricky to provide a direct translation. Something happens that makes it easy for something else to happen, and so you go ahead and do it. "Since I had a kid, I figured I would stop smoking". Only applicable after nouns.
182) ～を契機に ・ ～を契機として ・ ～を契機にして
See above, add formality
put ~ into it
Okay, I admit that one definition is a little dirty (to me), but it's a good broad definition for this phrase. The key point is that it's mostly used for intangibles, like when you "put some love into your cooking", or "put all your strength into your baseball swing".
184) ～を中心に ・ ～を中心として ・ ～を中心にして
~ becomes/is the core/center/focus/heart
Snag this sucker onto a noun and it does just what that definition implies - emphasize that noun as the most critical part of something else.
185) ～を通じて （をつうじて） ・ を通して （をとおして）
Through ~, ...
By means of ~, ...
Via ~, ...
You use this when some third-party helps in accomplishing something. "Through your powers combined, I am Captain Planet!". Again, only on nouns!
And that's it for today's grammar. Just six more entries to go!
