Children who fail to produce 50 words and two-word combinations at 24 months might be delayed in expressive language development. Toddlers also begin to combine words for more advanced sentence forms using a combination of syntax features and grammatical morphemes (Brown, 1973). In addition, they gain the meaning of the words. Bloom and Lahey (1978) termed this as children applying semantic-syntactic rules. As demonstrated, language milestones for children 2 to 3 years old is a complex integration of several factors and are achieved at different rates. Expressive Language Definition and Constructs Young children with limited expressive vocabulary are a concern for parents and early interventionists. As indicated by the ASHA's (2012) guidelines regarding typical milestones, by the age of three, children should be able to express themselves in a shared communication experience. According to Bzoch and League (1970), if a child has not mastered expressive communication milestones by age three, a developmental concern with expressive language is apparent. However, expressive language disorder is difficult to define due to its multidimensional nature. An article published in the American Academy of Pediatrics by Fischel, Whitehurst, Caulfield, and DeBaryshe (1989) stated that "developmental expressive language disorder is a frequently occurring condition in
