It is important to note before we move on that children do commit errors in their word learning.

Over Extension: This is where a child uses one word in particular to mean many objects at once. Ex: Child says 'dog' when she sees dogs, horses, cows, pigs, and sheep.
 
Under Extension: This is where just the opposite happens. Here a child uses one word to specifically mean only one object in particular. Ex: Child only calls his dog a 'dog'.
 
Idiosyncratic: Talking about something that isn't there. Ex: when someone takes the top off of an object the child gleefully shouts "weasel"!
 
Over regularization: In the beginning, children tend to ignore the irregularities of language such as the differences in the past tenses for walk-walked,vs. go-went, and hand-hands, vs.foot-feet. It is interesting how a child will say feet early on but at some point the child starts learning more language rulse and changes feet to foots and went to goed to go along with the rules he has learned. This is over regularization. Changing the word to a regular change that normally changes irregularly.
