2 Cognitive Exploration of Language and Linguistics
expression are meaningful to us as “signs” of something. In its widest sense, a
sign may be defined as a form which stands for something else, which we
understand as its meaning. For example, raising one’s eyebrows is understood
as a sign of surprise, whereas blowing one’s nose is usually not taken to be a
meaningful sign, but it may become one if it is intended as an expression of
protest. The three examples given above are illustrations of three possible
different types of signs, i.e. indexical, iconic and symbolic signs.
An indexical sign,orindex, points to something in its immediate vicinity,
as is suggested by the etymology of the Latin word index ‘pointing finger’. The
clearest case of an indexical sign is a signpost for traffic pointing in the direction
of the next town such as Bath. The signpost has the meaning: “Go in this
direction to get to Bath.” But facial expressions such as raising one’s eyebrows
or furrowing one’s brows are also indexical signs: They “point” to a person’s
internal emotional states of surprise or anger.
An iconic sign,oricon, (from Greek eikon ‘replica’) provides a visual,
auditory or any other perceptual image of the thing it stands for. An iconic sign
is similar to the thing it represents. The road sign that warns drivers to look out
for children near a school pictures two or three children crossing the road on a
zebra crossing. The image is of course only vaguely similar to reality since, at a
particular moment, only one or any number of children may be running across
the street, but its general meaning is very clear nevertheless. The idea of danger
caused by animals on roads is also pictured by iconic signs such as images of
cows, deer, geese, horses, toads, etc. Pictures of lorries, cars, tractors, cycles,
cycling paths, rivers, bridges, falling rocks, bends in the road, hairpin bends, etc.
are usually represented iconically. The above-mentioned gestural drawing of a
woman’s shape with one’s hands or the tracing of a spiral staircase with one’s
finger are, of course, also iconic signs.
Unlike indexical and iconic signs, a symbolic sign,orsymbol, does not have
a natural link between the form and the thing represented, but only has a
conventional link. The traffic sign of an inverted triangle is one such symbol: It
does not have a natural link between its form and its meaning “give right of
way”. The link between its form and meaning is purely conventional. The same
applies to military emblems, the pound sign £, almost all flags and, of course,
most of language. Thus, there is no natural link at all between the word form
surprise and its meaning. The term symbolic as used in linguistics is understood
in the sense that, by general consent, people have “agreed” upon the pairing of
a particular form with a particular meaning. This sense of symbolic goes back to
the original meaning of the Greek word symbolon ‘a token of recognition’ used
