difference between tachidomaru and yameru

[micronix]

in which circumstances can tachdomaru and yameru can be used?

[taikutsu]

（止める）やめる means to stop something or to stop doing something.

立ち止まる comes from 立つ（たつ）which means to stand, and 止まる（とまる） which means to stop moving. Looking up the specific meaning in a Japanese dictionary, it means someone stops walking.

That's a simple explanation anyway.
