Title vs. Entitle

entitled is a verb and titled is an adjective used AFTER a verb - "her new book, entitled 'Blahdy Blah', is out next week". Or, "She wrote a book about nothing titled 'Blahdy Blah'".

Clear as mud eh?

Both "titled" and "entitled" are verbs and both are adjectives as well. Furthermore, your example of "entitled" below, was not demonstrating use as a verb, but as an adjective. While they both have several definitions, they do overlap, and in some cases (particularly regarding the original question) are listed as synonyms with identical definitions.

What Cheri said.
"Having bought a book titled "Harry Potter and the Childrens Library" she was entitled to read it."

The meaning of entitle is slightly different to titled. Titled is meaning the title of which is "a book, the title of which is 'Harry Potter and the Children's Library'"
Entitled, is to name or give a title to
"she entitled the book 'Harry Potter and the Children's Library'"
Entitled has a secondary meaning, the general idea of which is to allow or give permission
"She was entitled to read the book titled 'Harry Potter and the Children's Library"

On another note, the Children's Library, is a posessive and so their should be " 's " at the end of it.

It only only be "She read a book entitled...". No question.

It could only be "She read a book entitled...". No question. That's what I meant to type, sorry, tired today.

I always find it funny when folks on the TV say stuff like, "My latest rap song entitled..." They just sound soooo ignunt! Why cain't they realize what they sayin is ignunt and git off the TV?

A number of the question's responses confuse the verbal usage of "entitled" with the adjectival usage of entitle, referring to a "just claim to recieve or do something."

Its seems the verbal usage of the words are very similar. The definition, according to the OED, of the verbal usage of "title" is

"give a name to (a book, composition, or other work)".

The word originally denoted a placard or inscription placed on an object.

The definition of the verbal usage of "entitle" is

"give (something, especially a text or work of art) a particular title"

and, archaically,

"give (someone) a specified title expressing their rank, office, or character".

It seems, technically, "title" is in reference to an object, and "entitle" is in reference to a person. However, in modern usage, the definition of the words is it the same; "entitle refers specifically, if we assume writing is an art, to art, including literature, painting, sculpting, music, and dancing.

imho porsche's comment is the one to follow if wanting to get the issue clearer

My boss always uses "entitled" to refer to a paragraph heading instead of "titled" or "subtitled". A google search and other comments suggest that major dictionaries say both mean the same thing though one normally associates "entitled" with being privileged or having a right to something. I looked up American Heritage Dictionary and Damon is right, they mean the same thing. But most dictionaries define it as a person being entitled to something. The Oxford Advanced Learner's Dictionary defines it as "feeling that you have a right to the good things in life without necessarily having to work for them".
