What's the opposite of 儿化？非儿化？ I'm looking for the way to express the opposite of 儿化 in Chinese.
Let's assume 老头儿（lǎotóur）is the standard and it's rarely ever without an 儿. 老头 in this instance would be an exception. I want to express this by saying it's the opposite of 儿化.
规范 seems to express this in a few ways:

口语中多儿化
在口语中常读儿化音
口语中一般儿化

Which is okay.
I'd be happier with something like:

老头是老头儿的非儿化。

I'm not sure that any such terminology exists.
I cannot think of a term that exactly refers to the version without erization corresponding to the same word with erization.
「非儿化」 refers to the property of the sound:

「头儿」 is 「儿化的 / 儿化音」.
「头」 is 「非儿化的 / 非儿化音」.

「去儿化」 refers to the process in which the erization is removed:
↑ 「去儿化」 is to 「儿化」 as &quot;decentralize&quot; is to &quot;centralize&quot;

「老头儿」去儿化之后得到「老头」。
「老头」是「老头儿」去儿化之后的结果。
