106. Than and as Object pronouns (me, him, her etc) can be used after as and than, especially in an informal style.

 • She is taller than me. 

• He earns as much as her.

• She doesn't sing as well as him. 

In a formal style, we prefer subject + verb after as and than

 • She is taller than I am. 

• He earns as much as she does. 

• She doesn't sing as well as I do. 

Note that a subject form without a verb (e.g. than I) is unusual in this structure in modern English.

 • He ran as fast as me. OR He ran as fast as I did. (More natural than ‘He ran as fast as I’.)
