What are some common language errors that children make in early childhood?

What will be an ideal response?

Due to a language acquisition process called fast mapping, children quickly attach new
words to the appropriate concepts. The "whole-object assumption" leads children to
surmise that the names of objects (such as "kitty") refer to the entire object (the body,
the head, the legs, the tail, and so on) rather than just one feature (such as the color of
the fur). Despite the incredible advances in language development, children are prone
to certain errors. One error is "overregularization.". With this error, children assume
that grammatical rules are applied universally. It is the exceptions to our language that
are the hardest to learn. Children learn, for example, that adding an "-ed" to words
makes them past tense. So walk becomes "walked.". Children overuse these rules so
that go becomes "goed.".
