Your sentences need to start with a capital letter and end with a full stop. Ellipses have three dots not two.

@Umbivalent

Dependent is the American spelling. UK is dependant.

Dependent is more usually an adjective in the UK. Dependant is a noun.

My dependent niece needs me to fund her. She is my only dependant.

[dubyalass]

Agree with @oneglassandpuzzled.

@Umbivalent

Actually it's dependant.

PPs are confusing it with independent.

No, in the OP's sentence it's dependent.

[shinyblackdog]

Previous four posters are correct. Dependant is a noun.

[TheGirlOnTheLanding]

As @BobbinThreadbare123 said above, the 'a' spelling used in the UK is for a different meaning than the one in your sentence. The 'e' spelling is the correct one in this context.

If you were talking about your dependants (ie the people who were financially dependent on you) you'd use the noun.
