Thankyou greatly to Gerri Lynn Baxter for providing this much needed verbal outline!
STRONG VS. WEAK VERBS
Strong verbs change their vowel sounds when they switch tense:
swim
swam
swum
sing
sang
sung
ride
rode
ridden
etc. and so on.
Weak verbs add a suffex to switch tense:
add
added
added
walk
walked
walked
zoom
zoomed
zoomed
etc., and so on.
Then there are the irregular verbs that change their entire spelling when switching tenses:
is
was
been
has
had
had
etc., and so on.
ACTION VS. LINKING VERBS
What you guys are really squawking about in this part of the thread are linking verbs versus action verbs. As from the Grammar Bytes! website, "Linking verbs do not express action." The direct Linking Verb link. The action isn't carried on the verb. Read the page because the linking issue isn't as straight forward as just saying to be is always a linking verb.
ACTIVE VS. PASSIVE SENTENCE CONSTRUCTION
Active sentences have the construction:
Actor action acted upon.
Passive sentences have the construction:
Acted upon (to be) action actor.
or
Acted upon (to be) actor action.
Examples:
Living with gusto is what many Americans yearn for.
Many Americans yearn to live with gusto.
Mary pushed the table across the room.
The table was pushed across the room by Mary.
See the difference?
