chunks are 'ready to go', and require little or no

additional processing.

Some lexical chunks have 'slots' which can take

different words according to the situation, provid-

ing a scaffold for quick, but flexible, language use.

For example, ' (person) thinks nothing of

ing (verb)' can provide the preformulated

platform for many different realizations, such as

Diane thinks nothing of hiking 20 miles, or He

thinks nothing of teaching six classes a day. The

ability to use preformed lexical chunks allows

greater fluency in speech production. The use of

lexical chunks can aid the listener as well. Because

lexical chunks can be recognized as individual

wholes, this spares the listener some of the

processing effort required to interpret an utter-

ance word-by-word.

It has been argued that lexical chunks also play a

part in vocabulary and grammar acquisition. Once

a chunk is known, it can be analysed and

segmented into its constituent words. This can

occur when some variability is noticed in a lexical

chunk. For example, after having heard the phrase

How are you today? several times, it may be

acquired as a chunk with the meaning of 'a

greeting'. However, the learner may later notice

the phrases How are you this evening? or How are

you this fine morning?. At that point, the learner

may realize that the underlying structure is

actually How are you ?, where the slot

can be filled with a time reference. The learner is

then aware that what fits in the slot is a separate

unit from the rest of the phrase, which opens the

door to learning that lexical unit. Eventually, the

entire lexical chunk may be analysed into separate

words, although it may continue to be stored as a

whole because of its utility. Because this segmen-

tation also involves syntax, it has been suggested

that it can also lead to grammatical acquisition.

Lexical chunks

Although vocabulary has conventionally been

conceptualized as individual words, it has now

become clear that much of lexis consists of

sequences of words which operate as single

units. Traditional approaches have long dealt

with multi-word units (MWU), wherein a single

meaning is attached to more than one word, for

example, phrasal verbs ('give up'), compounds

('freeze-dry'), and idioms ('burn the midnight

oil'). But corpus-based research has shown that

collocation (the tendency for words to occur

together in discourse) extends far beyond the

level of such MWUs. In fact, it appears quite

common for longer sequences of words to pattern

together. Some of these recur frequently enough

to be treated as units in their own right, e.g. to

make a long story short. Numerous terms have

been coined to refer to this type of sequence, but

the most commonly used are lexical chunks and

lexical phrases.

One reason these lexical chunks are so common is

that they are typically related to functional

language use. For example, the above lexical

chunk is often used in summarizing, while Have

you heard the one about ? is reserved for

beginning a joke or humorous story. Lexical

chunks like these are institutionalized as the

most efficient and most familiar linguistic means

to carry out language functions. As such, they

facilitate clear, relevant, and concise language use.

Because of their functional usage, knowledge of

lexical chunks is essential for pragmatic compe-

tence.

There is a good psycholinguistic basis for believing

that the mind stores and processes these chunks as

individual wholes. The main reason stems from

the structure of the mind itself. It can store vast

amounts of knowledge in long-term memory, but

is only able to process small amounts of it in real-

time, such as when one is speaking. In effect, the

mind makes use of a relatively abundant resource

(long-term memory) to compensate for a relative

lack in another (processing capacity) by storing a

number of frequently-needed lexical chunks as

individual whole units. These can be easily

retrieved and used without the need to compose

them on-line through word selection and gram-

matical sequencing. This means there is less

demand on cognitive capacity, because the lexical
