Errors in early word use or developmental errors are mistakes that children commonly commit when first learning language. Language acquisition is an impressive cognitive achievement attained by humans. In the first few years of life, children already demonstrate general knowledge and understanding of basic patterns in their language.
A spectrogram of a male speaker saying the phrase "nineteenth century". There is no clear demarcation where one word ends and the next begins. It is a well-established finding that, unlike written language, spoken language does not have any clear boundaries between words; spoken language is a continuous stream of sound rather than individual words with silences between them.

Language acquisition usually refers to first-language acquisition. It studies infants' acquisition of their native language , whether that is a spoken language or a sign language, [ 1 ] though it can also refer to bilingual first language acquisition (BFLA), referring to an infant's simultaneous acquisition of two native languages.
The ability for learners to develop their language skills depends to a large extent on the type of language input that they receive. For input to be effective for second-language acquisition, it must be comprehensible. Merely being immersed in a second-language environment is no guarantee of receiving comprehensible input.
The term universal grammar refers to the set of constraints on what a possible human language could be. Within approaches that accept universal grammar, language acquisition is viewed as a process of using sensory input to filter through the set of possible grammars that conform to UG.
Krashen stresses yet again that speaking in the target language does not result in language acquisition. Although speaking can indirectly assist in language acquisition, the ability to speak is not the cause of language learning or acquisition. Instead, comprehensible output is the effect of language acquisition. [3] [5]
In cognitive psychology, fast mapping is the term used for the hypothesized mental process whereby a new concept is learned (or a new hypothesis formed) based only on minimal exposure to a given unit of information (e.g., one exposure to a word in an informative context where its referent is present).
