Here's a breakdown of what the phrase is trying to convey:
* Act: This refers to the action of doing something.
* Injecting: This implies adding something, like a suffix, to a word.
* Suffix: This is a word part added to the end of a word to change its meaning or grammatical function.
Therefore, "act of injecting suffix" could be interpreted as adding a suffix to a word.
Example:
The act of injecting the suffix "-ing" to the verb "walk" creates the present participle "walking".
More precise terms for adding suffixes:
* Suffixation: This is the technical term for adding a suffix to a word.
* Adding a suffix: This is a more straightforward way to describe the process.
