The lexeme is also useful in handling expressions like red tape 'silly detailed unnecessary official rules that delay action' (1) and kick the bucket 'die' (2) as opposed to red tape 'tape which is red' (3) and kick the bucket 'strike the bucket with one's foot' (4).
(1) It took a long time to cut through the red tape and get the
building started.
(2) Have you heard that Fred Jones has kicked the bucket?
(3) He made up the parcel with red tape.
(4) The cow kicked the bucket so that it overturned and the
milk ran out.
The underlined expressions in (3) and (4) are straightforward syntactic
constructions (NP made up of premodifier + head, and a clause fragment
made up of V + dO, respectively) whose meaning is entirely predictable
from the meaning of each morpheme. In the first two examples, on the other
hand, the meaning of the underlined expression is not predictable
from the meaning of each morpheme; instead, these expressions must be learned
as units. We say that the original constructions have been lexicalized,
i.e. made into lexemes. Such lexemes are referred to as idioms:
they are said to have idiomatic meaning (i.e. meaning not predictable
from the meaning of each morpheme making up the lexeme) as opposed to the
literal meaning of the underlined expressions of (3) and (4).
Two lexemes which have the same form but different sense
are said to be homonyms: BANK 'land on either
side of a river' v. 'financial institution', EAR 'hearing
organ' v. 'cluster of grains'. A polysemous lexeme, on the other
hand, is one lexeme with two or more related senses (e.g. FOOT,
HEAD, PAPER).
Homonyms typically correspond to two different lexemes in another language;
cf. EAR1 (N. øre) and EAR2
(N. aks). But this in itself is not a sufficient criterion for homonym
status: cf. the polysemous PAPER, which has a separate
Norwegian counterpart for each major sense: 'paper'1 (N. papir),
'paper'2 (N. avis), 'paper'3 (N. foredrag),
'paper'4 (N. eksamensoppgave), 'paper'5 (N.
tapet).
2. The semiotic triangle
Two corners of the so-called semiotic triangle (EGTU p. 44) (form
and sense) correspond to what we earlier called the linguistic sign
(cf. lecture 1).
The third corner (labelled referent3 below) would
normally be labelled denotatum (cf. the use of the verb denote
in EGTU 2.4.2):
| FORM | SENSE | REFERENT3
(=DENOTATUM) |
REFERENT1 |
| girl | 'young female human being' | any person about whom the lexeme may be used (i.e. what the lexeme denotes) | The particular girl I'm talking about (referring to) when I say There is a girl outside who wants to talk to you. |
| book | 'a set of printed pages fastened together in a cover' | any object about which the lexeme may be used (i.e. what the lexeme denotes) | The particular book I'm talking about (referring to) when I say The book I read last night was boring. |

It is usually easier to represent sense contrasts and sense relations
than the actual sense of simple lexemes. Thus, in each group below it is
easy to show how the individual lexemes relate to each other by referring
to elements of meaning such as 'male'/'female' and 'adult'/'young', whereas
the sense of the first element in each group is less easy to represent:
verbs of communication: speak, talk, say, claim, assert, maintain, ...
verbs of perception: see, hear, feel taste, sense, notice, observe, ...
verbs of cognition: think, believe, know, realize, understand, assume, ...
The following is intended to illustrate the dimensions along which the sense of movement verbs can vary: contact with the ground, part(s) of body touching the ground, speed of movement, direction of movement, purpose, etc.
go the general verb for movement
walk on two feet, constant contact with ground
crawl on hands and knees, constant contact with ground
hop on one foot, intermittent contact with ground
run on two feet, intermittent contact with ground
stride walk quickly with long steps
mince walk in an unnatural way, taking short steps and moving your hips
pace walk with slow regular steps, usually back and forth
tiptoe walk quietly with your heels off the ground
creep move quietly, so as not to be seen/hear
prance walk in a confident way in order to make people notice or admire you
sidle walk towards sth/sb slowly and quietly,
as if you do not want to be noticed
Other adjectives may share a basic sense ('of great size in accordance with a given norm') but vary along an intensity scale: BIG - HUGE - ENORMOUS.
Since one important function of adjectives is that of modifier in a
noun phrase, it is possible to detect a good deal of systematicity in the
way a given adjective tends to collocate (= occur together) with
a given noun. The following are examples of typical collocations
with adjectives sharing the basic sense 'not real': false teeth,
spurious argument, counterfeit money, artificial flowers,
fake jewellery, mock exam.
