The spelling of "dis entitled" may seem a bit confusing, but it is actually quite straightforward when broken down phonetically. The word is pronounced /dɪsɪnˈtaɪtld/, with the stress on the second syllable and the "en" pronounced as a schwa sound. The prefix "dis" means "not" or "lack of", while "entitled" means having the right to something. Therefore, "dis entitled" refers to someone who does not have the right or claim to something they may have previously thought they did.
The word disentitled is derived from a combination of the prefix dis- and the verb entitle.
The prefix dis- is of Latin origin and means opposite or not. It is typically used to indicate negation or reversal.
The verb entitle comes from the Old French word entitler, which means to assign a title or right to. It ultimately traces back to the Latin word intitulare, which means to give a title to.
Therefore, disentitled combines the negating prefix dis- with the verb entitle to form a term that means to not have a right or title to something, or to be deprived of a claim or entitlement.
