| semantics | the study of meaning |
| syntax | the arrangement of words to make a sentence |
| morphology | the formation of words from morphemes |
| phonology | sound systems and how they can communicate meaning |
| pragmatics | factors that influence the choices producers make |

| two word stage | two word combinations (18-24 months) |
| telegraphic stage | three and more words combined (24-36 months) |
| post-telegraphic stage | more grammatically complex combinations (36+ months) |
| language acquisition device (LAD) | the human's inbuilt capacity to acquire language |
| phonemic expansion | when the variety of sounds produced increases |
| phonemic contraction | when the variety of sounds is reduced |
| consonant | a speech sound produced when the vocal tract is so blocked/restricted that there is audible friction |
| vowel | a sound made without closure or audible friction |
| diphthong | a vowel where there is a change in quality during a syllable e.g. "ie" |
| deletion | omitting the final consonant in words |
| substitution | substituting one sound for another |
| addition | adding an extra vowel sound to the end of words, creating a CVCV pattern |
| assimilation | changing one consonant or vowel for another |
| reduplication | repeating a whole syllable |
| consonant cluster reductions | consonant clusters can be difficult to articulate, so children reduce them to smaller units |
| deletion of unstressed syllable | omitting the opening syllable in polysyllabic words |
| holophrase | a single word expressing a whole idea |
| vocative | a form used to address a person |
| social interactionists | believe child language develops through interaction with carers |
| positive reinforcement | when behaviour is rewarded |
| negative reinforcement | when an undesirable behaviour is unrewarded with the intention it will not be repeated |
| behaviourists | believe that language is acquired through imitation and reinforcement |
| overextension | when the word used to label something is stretched to include things that aren't normally part of its meaning |
| underextension | when the word used to label is reduced to include only part of its normal meaning |
| categorical overextension | when the name for one member of a category is extended to all members of the category |
| analogical overextension | when a word for one object is extended to one in a different category, usually based on physical or functional connection |
| mismatch statements | one word sentences that appear abstract, child makes a statement about one object in relation to another |
| labelling | linking words to the objects which the producer is referring to |
| packaging | exploring labels e.g. overextension and underextension |
| network building | making connections between words, understanding similarities and opposites in meanings |
| deixis | lexis that point towards towards something and place words in context e.g. these |
| free morpheme | one that can stand alone as an independent word e.g. apple |
| bound morpheme | one that cannot stand alone as an independent word e.g. "-er" "-s" |
| cognitive theorists | believe that language acquisition is part of a wider development of understanding |
| virtuous error | syntactic error which reveals some understanding of standard syntax |

| practising | using language when no adult is present |
| child directed speech (CDS) | speech patterns used by parents/care givers when communicating with young children; involving simplified vocabulary, melodic pitch, repetitive questioning |
| language acquisition support system (LASS) | child's interaction with the adults around them, and how it supports language development |
| object permanence | the awareness that objects continue to exist even when they are no longer visible |
| scaffolding | process of transferring a skill from adult to child and then withdrawing support once mastered |
| nativists | believe that humans have an inbuilt capacity to acquire language |
