Today’s Question

もう夏(なつ)ですね。もみじの はっぱは いまは みどり ですが、あきには ____。
もみじ = a maple (tree)

  1. あかい でしょう
  2. あかい です
  3. あかく  なります
  4. あかに なります

Today’s Grammar Point: ~く/~に なります

なります is the most common word that describes a change. Although なります can be used with many other words and have various meanings, the most basic meaning is “to become ~.”

Connection

  • [noun] + に + なります
  • [なadjective] + に + なります
  • [いadjective stem] + く + なります
    “いadjective stem” means “いadjective” minus the ending い

Examples

ジョンさんは えいごの せんせいに なりました
John became a teacher of English.

もうすぐ 五時に なります
Soon it will be 5 o’clock.

わたしは ピアニストに なりたいです。
I want to be a pianist.

しんごうが あかに なります
The traffic light will turn red. (When the change is mechanical, we use a noun form of the colour red, so the particle に is required.)

はやく げんきに なってください。
Please get well soon.

ことしから てつづきが かんたんに なりました
The procedure was been made simpler this year. (This year, the procedure became simpler.)

せいとが いえに かえって、学校は しずかに なりました
Students went home and the school became quiet.

5時ごろから みせが いそがし なりました。(いそがし = busy)
The shop got busy from around 5 pm. (This suggests it wasn’t very busy until 5 pm.)

らいげつから このサイトが もっと おもしろ なります。(おもしろ = interesting)
This site will become more interesting from next month.

えいがを みて、メアリーさんは かなしなりました。(かなし = sad)
Mary watched the movie and felt sad.

もみじの はっぱが あか なります。(あか = red)
The maple leaves will turn red. (When the change is natural/gradual, we prefer using the いadjective form (if available), so the ending い of あかい changes to く and なります gets added.)

Answer to Today’s question: c

The sentence says: “It is already summer. Maple leaves are green now but they _____ in autumn.”

Because it is talking about maple leaves, not any leaves, the blank should be filled with “turn red” or “become red.” You need to choose the verb with the meaning of “turn/become.” です/でしょう  do not have that meaning. The best answer is c. They turn “red” and this process is a natural, gradual process, we prefer the いadjective, あかい to the noun form あか (shown in the choice d).

A bit more about a colour change

There are 6 colour words in Japanese which can be used as a noun as well as an いadjective by adding い afterwards. They are:

あか (red), あお (blue), しろ (white), くろ (black), きいろ (yellow) and ちゃいろ (brown).

When the colour of something changes to one of the above 6 colours, you have to think of how the change occurs.

If the change is natural and gradual, like leaves turning red or yellow, an いadjective is used, so the sentence should end in ~く なります.

If the change is mechanical, like turning a switch, we prefer using the noun form, so the sentence should end in ~に なります.

(×)しんごうが あか なりました。

    […] Now if you want to describe a change, for things, we use 太くなる and for a person or an animal, we use 太る. (For explanation about [いadjective stem] + く + なる, please read this post.) […]
