How to use "Ama ri" and "Ama ri ni mo"

[cafechocolate]

Konnichiwa minna-san. Please help me to solve this problem. Thank u so much.

According to the Japanese dictionary, both "ama ri" and "ama ri ni mo" mean "too much" but I don't know how different to use "ama ri" and "ama ri ni mo". Seem "ama ri" usually goes with negative verb or negative adjective, such as "Watashi wa terebi wo mimasen".

 

[Toritoribe]

"Amari ni (mo)" means too much/many, whereas "amari" is not much/many in a negative sentence.
e.g.
Kare wa amari ni (mo) terebi wo misugiru.
He watches TV too much.

Watashi wa amari terebi wo mimasen.
I don't watch TV much.

"Amari" can mean too much/many only when used in a subordinate clause. It's often pronounced "anmari". ("Amari ni (mo)" is more common for too much/many even in this usage.)
e.g.
A[n]mari terebi wo misugiru to, me ga tsukareru yo.
If you watch TV too much, you'll get eye strain.

Why is there a need to say mi + sugiru, when amari, should already emphasize the "too much" part?

 

[Yzlot]

The mi + sugiru is meant to quantify the action of watching TV. A[n]mari expresses too much, of a quantifiable action. Simply watching TV isn't quantifiable, but spending time watching TV is. Hope you understood that.

This would be the lit translation: If you pass too much time watching TV, you'll get eye strain.
