“…The similarities refer to the theme of the study, including grammar, case grammar, grammar attributes, and research method. The differences lies in several aspect, including shape grammars as a reverse engineering method (Eilouti, 2019) and block morphological analysis to generative urban design (Wang et al, 2020), context sensitive fusion grammars and fusion grammars with forbidden context (Lye, 2022b), reflect of term in grammar attribute to be able to change the term (Kramer et al, 2021), context free grammar for the e-positivity of the trivariate (Chen, W.

S., Roscoe, R. D., Allen, L. K., Likens, A. D., & McNamara, 2022), linguistic and grammar in the field of connectives (Cuenca, 2022), and the relationship between nasal harmony and word-internal language mixing in Paraguayan Guarani…”
