future tense n
a tense form used to indicate that the event described by a verb will take
place at a future time. For example in the French sentence:
Je partirai demain.
I leave + future tomorrow.
the future tense ending -ai has been added to the verb infinitive partir
(=leave). English has no future tense but uses a variety of different verb
forms to express future time (e.g. I leave tomorrow; I am leaving tomorrow;
I will leave tomorrow; I am going to leave tomorrow). Will in
English is sometimes used to indicate future time (e.g. Tomorrow will be
Thursday) but has many other functions, and is usually described as a
MODAL verb.
fuzzy adj
a term used by some linguists to describe a linguistic unit which has no
clearly defined boundary. These units have “fuzzy borders’’, e.g. the
English words hill and mountain. Another term used for a gradual transition
from one linguistic unit to another is gradience.
