I hereby pronounce you spaghetti!

Pizza Hut really does come up with the most unique of uses of words. In this advertisement about their new soft shell crab pasta, they happen to say "marrying succulent soft shell crab with al dente pasta".

In discourse structure, we learnt about declaratives, and the definition of declaratives and for the verb "marrying" is shown below:

Declarative (from Longman dictionary of contemporary English)
de‧clar‧a‧tive

SL a declarative sentence has the form of a statement

Declarative (from Longman dictionary of language teaching and applied linguistics)
A speech act that changes the state of affairs in the world.

Marry
mar‧ry S1 W2 past tense and past participle married, present participle marrying, third person singular marries

1 [intransitive and transitive] if you marry someone, you become their husband or wife [↪ married]:

People in higher social classes are more likely to marry late (=when they are older than is usual).

! In spoken English, get married is more common than marry.

2 [transitive] to perform the ceremony at which two people get married:

The priest who married us was really nice.

3 [transitive] to find a husband or wife for one of your children

5

not the marrying kind

not the type of person who wants to get married:

From the definitions as shown, we realise that the contemporary English definition of declarative and the Applied linguistic dictionary for declarative are quite similar. As linguists, our lexical stock would lead us to think that the declarative is the linguistic definition, which also includes that a person must be authorised to perform the declarative act. In the case of the commercial, we realise that "marry" here needs a person who has the power bestowed on him/her to conduct the ceremony. In this case... the sentence implies that Pizza Hut is the one that married the pasta and soft-shell crab together. However, if we go by Searle's speech act theory, then this declarative doesn't really stand, as Pizza Hut is not authorised.

Then again, the other definition of "marry", in the sense of "marry up", would completely debunk this intuition. As such, what we realise here is that there is a misunderstanding, that where one who is not that exposed to the meaning of "marry up" would find it a completely absurd relationship.

How would you like to attend the wedding ceremony of soft-shell crab and al-dente pasta? They both have the same NP composition... =)
