何と言っても～

About

The phrase 何なんと言いっても is a combination of 何なん (which is always read as なん in this context), the quote marker と, and ～ても, which modifies 言いう and altogether gives us a literal meaning of "no matter what (one) says".

何なんと言いっても is used to emphasize one option of many as being "the most X".

何なんと言いっても has a spoken feel to it, and is most commonly used in spoken casual, or sometimes spoken polite scenarios.

何なんと言いっても can be contracted in spoken scenarios to 「なんてったって・なんたって・なんつったって」.

E.g. 何なんと言いっても自分じぶんのベッドが一番いちばん落おち着つくよね。 "Your own bed is undoubtedly the most relaxing."

E.g. 暑あつい日ひは何なんと言いっても冷ひえたビールに限かぎる。 "On a hot day, cold beer is undoubtedly the best."

E.g. 沖縄おきなわの見みどころは何なんと言いってもその美うつくしい海うみです。 "Okinawa's best part is undoubtedly its beautiful ocean."
