When analyzing pidgin development, what is meant by the 'substrate' influence on grammar?

When analyzing pidgin development, 'substrate' influence on grammar refers to the impact of the native languages of the less dominant groups on the grammatical structure of the pidgin. Substrate languages are those spoken by the populations who are often in a position of lower social or economic power when the pidgin is forming. While the vocabulary of a pidgin typically comes from the superstrate language (the language of the dominant group), the grammatical rules and patterns can be influenced by the substrate languages. This can include features such as word order, the use of specific grammatical particles, or phonological patterns. For example, a pidgin formed in an area where the substrate languages use a Subject-Object-Verb (SOV) word order might show a tendency towards that word order even if the superstrate language uses a different order. The substrate influence represents the linguistic legacy of the speakers whose native languages contributed to the formation of the pidgin.
