Cross-Linguistic Influence

Examines speakers or writers who apply knowledge from a mother-tongue language to a second language.

When these different languages interact in the mind, they affect the linguistic performance and/or the linguistic development of the individual concerned. The results can show positive and/or negative transfer.


Focuses on language development through the incremental acquisition of meaningful chunks, or lexical items of more than one word, such as Phrasal verbs, Collocations, and Idioms. E.g. “street sign “, “look out for “, “as I was saying “, “If I were you”, andput your foot in it“.

Corpus Linguistics

Examines language as it is used in “real word” samples (corpora) or “real world” texts.

By looking at concordances, (an alphabetical list of the principal words used in a book or body of work) a corpora compares different usages of the same word, analyzes keywords, word frequencies, phrases and idioms.

This is helpful if wanting to learn the most common expressions, phrasal verbs, idioms, or vocabulary used in a specific industry or realm.


Looks at the psychological and neurobiological factors that enable humans to acquire, use, understand and produce language.

Psycholinguistics covers the cognitive processes that make it possible to generate a grammatical and meaningful sentence out of vocabulary and grammatical structures, as well as the processes that make it possible to understand utterances, words, text, etc.
