is
running. 
The sheep 
are
running. 
In the above, the number of the noun is not marked on the noun itself (
sheep
does not inflect 
according to the regular pattern), but it is reflected in agreement between the noun and verb: 
singular number triggers 
is
, and plural number 
are
. 
The bird 
is
singing. 
The bird
s
are
singing. 
In this case the number is marked overtly on the noun, and is also reflected by verb agreement. 
However: 
The sheep can run. 
In this case the number of the noun (or of the verb) is not manifested at all in the surface form of 
the sentence, and thus ambiguity is introduced (at least, when the sentence is viewed in 
isolation). 
Exponents of grammatical categories often appear in the same position or "slot" in the word 
(such as prefix, suffix or enclitic). An example of this is the Latin cases, which are all 
suffixal: 
ros
a
, 
ros
ae
, 
ros
ae
, 
ros
am
, 
ros
ā
("rose", 
in 
the nominative, genitive, dative, accusative and ablative).

Categories can also pertain to sentence constituents that are larger than a single word (phrases, or 
sometimes clauses). A phrase often inherits category values from its head word; for example, in 
the above sentences, the noun phrase 
the birds
inherits plural number from the noun 
birds
. In 
other cases such values are associated with the way in which the phrase is constructed; for 
example, in the coordinated noun phrase 
Tom and Mary
, the phrase has plural number (it would 
take a plural verb), even though both the nouns from which it is built up are singular.
