Contributed by: Mark Greenberg

ResourceFunction["WordPrefix"][wd]

returns wd divided into its prefix, if there is one, and the rest of the word.

Details and Options

The argument wd must be a string.

The rules for identifying prefixes are based on common English words in WordList.

To split off multiple prefixes from one word, nest ResourceFunction["WordPrefix"].

ResourceFunction["WordPrefix"] has the attribute Listable.

Separate a word from its first prefix:

In[1]:=

Out[1]=

Separate a word from multiple prefixes:

In[2]:=

Out[2]=

Separate prefixes in a list of words:

In[3]:=

Out[3]=

Whether part of a word is a prefix or a root is sometimes a judgment call. WordPrefix attempts to make sensible judgments in those cases:

In[4]:=

Out[4]=
