What did Turnbull & Justice 2012 say in regards to syntax?
- In their environments, most ch hear simple syntax
- grammatically good utterances with simple noun phrase and verb structures
- However, ch who hear complex syntax more in their environments produce greater amounts of complex syntax at an earlier age than ch who hear complex syntax less often
e. g., “the cat ate her food!”
When do ch master grammatical morphemes?
Around 18 mo when they start to put two words together

How do we measure morphosyntactic skills?
- we calculate MLU, or mean length of utterance
- instead of counting words, we count actual morphemes (free and bound)
What is MLU?
Mean Length of Utterance (number of morphemes in a sentence)
“We wanted to eat cookies” is how many words and how many morphemes?
5 words, 7 morphemes
“The three boys wanted five candies” is how many words and how many morphemes?
6 words, 9 morphemes
“We played all day with my friend’s toys” is how many words and how many morphemes?
8 words, 11 morphemes
“He’s going to cook eggs and bacon” is how many words and how many morphemes?
7 words, 10 morphemes

“I need to get my shoes and socks on because the stones will hurt my feet”
