✔ Explanation:
Each example shows how the prefix changes the base word's meaning:
-
anti-: "anti" + "biotic" = against life (bacteria).
-
bi-: "bi" + "cycle" = two wheels.
-
dis-: "dis" + "agree" = not agree.
-
im-: "im" + "possible" = not possible.
-
mid-: "mid" + "night" = halfway through the night.
-
mis-: "mis" + "understand" = understand incorrectly.
-
non-: "non" + "fiction" = not fictional.
-
over-: "over" + "cook" = cook too much.
-
pre-: "pre" + "view" = see before it happens.
-
re-: "re" + "write" = write again.
-
semi-: "semi" + "circle" = half a circle.
-
sub-: "sub" + "marine" = under the sea.
-
un-: "un" + "happy" = not happy.
-
under-: "under" + "cooked" = not cooked enough.
These examples help illustrate how prefixes modify meaning in English words.
