Many definitions of language have been proposed. Henry Sweet, an English phonetician and
language scholar, stated: “Language is the expression of ideas by means of speech-sounds
combined into words. Words are combined into sentences, this combination answering to that of
ideas into thoughts.” The American linguists Bernard Bloch and George L. Trager formulated the
following definition: “A language is a system of arbitrary vocal symbols by means of which a
social group cooperates.

Language
A language is a system of signs having meaning by convention. In this sense, language need not
be confined to the spoken word. Traffic signs, for example, form a minilanguage, it being a matter
of convention that [hazard] means “hazard ahead” in some countries. It is distinctive of languages
that linguistic units possess meaning by convention, and linguistic meaning is very different from
what is called natural meaning, exemplified in statements such as “Those clouds mean rain” and
“The fall in pressure means the valve is malfunctioning.”
