i have bought a macbook pro 13 inch and i cannot find microsoft word

Apple OS X includes access to Apple Pages

Pages - Apple

Word, and to a larger extent Microsoft Office are available from Microsoft

Microsoft Office for Mac – Microsoft Store

Unlike most computer distributors Apple does not bundle demoware, crapware or bloat with their OS

Macs do not come with MS Word, you have to purchase it from MS. However, you can download Pages from the AppStore free.
