Sentential Ambiguity
1. Ambiguity: definition
 a term used to describe an expression that can be interpreted in more than
one way word, a phrase, or a sentence with multiple meanings
2. Two types of ambiguity
 lexical (semantic) ambiguity
 due to ambiguity in the meaning of one or more of the words in the
sentence:
a word or an expression can be interpreted in more than one way
because it has multiple meanings

2. You will get a burning sensation.

 He went to buy arms.

 lexical ambiguity is created by two types of semantic relations among
words: polysemy and homophony
 polysemy occurs where a word has two or more meanings
same word has multiple meanings:
 bright:
(1) shining
 to glare: (1) shine intensely
 a deposit: (1) minerals in the earth
(2) intelligent
(2) to stare angrily
(2) money in the bank
 homophony exists where a single form has two or more entirely
distinct meanings
two distinct words use the same sound string:
same spelling
 bank
bank1 – a financial institution
bank2 – a small cliff at the edge of a river
 club
club1 – a social organization
club2 – a blunt weapon
 bear
to bear – tolerate
bear – an animal
different spelling
 piece
 peace
 write
 right

 bare
 structural (syntactic) ambiguity
 due to ambiguity in the syntactic structure of the sentence
the rules of syntax permit different structures for the same linear order
of words

 prepositional phrases after the verb are often structurally ambiguous
