Grammar Notes for Dialogue 4

Grammar Note 1 V-stemすぎる
 

すぎる verb ("pass/exceed") can also be attached to a verb stem (Verb stem + すぎる) and express "do something too often/too much/excessively." The negative form of this construction requires さ before すぎる ("do something too little/too infrequently").

行き/() すぎる go/come too often 行かな/() さすぎる go/come too infrequently
し/やり do (it) too much しな do (it) too little
使い use (it) too much 使わな use (it) too little
watch (it) too much 見な watch (it) too little
食べ eat too much 食べな eat too little
飲み drink too much 飲まな drink too little

The 食べすぎ in the dialogue (食べすぎなんじゃない? "That's overeating, isn't it?") is a noun form of 食べすぎる. This usage is fairly common.

A: ワインを飲んだら、頭がいたくなってきたよ。 After I drank wine, I began to have a headache.
B: それはワインの飲みすぎだよ。 That is overdrinking of wine.
     
たばこのすいすぎにはちゅういしましょう。 Be careful with oversmoking.
Grammar Note 2 Negative Request (Vないで下さい)
 

Earlier, we learned to use the Vて form to create request forms (e.g., 食べて下さい "[Please] eat"). To create a negative request form, we use the plain negative verb (Vない) + で form.

て-form

(下さい)   Plain Negative Verb
(下さい)
 
行って/来て (下さい) Please go/come. 行かない/()ない (下さい) Don't go/come.
して/やって Please do it. しない/やらない Don't do it.
使って Please use it. 使わない Don't use it.
見て Please look at it. 見ない Don't look at it.
食べて Please eat. 食べない Don't eat.
飲んで Please drink. 飲まない Don't drink.

Don't confuse this negative request form and the negative て-form of the verb Vて → Vなくて. Study the following differences.

コンピュータを使わないで下さい。 Please don't use computers.
コンピュータを使わなくてもいいですよ。 You don't have to use computers.
コンピュータを使わなくて下さい。 [ungrammatical]

コンピュータを使わないでもいいですよ。
