- Bound morpheme
In
etymology , a bound morpheme is aroot morpheme that cannot stand alone as an independent word. To determine if a root is bound, strip the root of all of itsaffix es (prefix es andsuffix es). If the remaining root is not a word, that root is a bound morpheme. Thus, the root is only used when it is "bound", i.e. connected, with a prefix or suffix.Examples
The root "gress" is associated with motion (for example e"gress" or retro"gress"). However, the word "gress" is not found in an English dictionary, so "gress" is a bound morpheme.
To identify the root morpheme of "ambidexterity," remove the prefixes and suffix:
:"ambidexterity" → (am)(bi) dexter (ity).
The resulting root is "dexter;" a dictionary reveals that this is not an English word. Therefore "dexter" is a bound morpheme.
However, "freeze" in "antifreeze" is a free (non-bound) morpheme.
:"antifreeze" → (anti) freeze.
The root here is "freeze;" a dictionary will confirm that this is its own word. Therefore "freeze" is a free morpheme.
Affixes
Affixes are themselves bound morphemes because they are used only when attached to a root morpheme and/or another bound morpheme.
Common English bound morphemes include: "-ing", "-ed", "-er", and "pre-".
