verb entailment  (see paper below)
 
The impor-
tant distinction is that while in <b>a paraphrase the two
verbs are semantically equivalent, entailment is a di-
rectional, or asymmetric,</b> relation: one verb entails
the other, but the converse does not hold. For ex-
ample, the verbs buy and purchase paraphrase each
other: either of them can substitute its counterpart in
most contexts without altering their meaning. The
verb buy entails own so that buy can be replaced with
own without introducing any contradicting content
into the original sentence. <b>Replacing own with buy,
however, does convey new meaning.</b></p>
