Singular Possessive: Lucas’s or Lucas’?

When forming the singular possessive of Lucas, both Lucas’s and Lucas’ are acceptable, though different style guides have preferences.

Lucas’s

The form Lucas’s is endorsed by the Chicago Manual of Style, one of the most respected style guides in the world. According to this rule, you add an apostrophe followed by an “s” to show possession, even if the name ends in “s.”

• Example sentence: Lucas’s dedication to his craft is unmatched.

In this sentence, Lucas’s dedication indicates that the dedication belongs to Lucas, and the apostrophe followed by an “s” clarifies this.

Lucas’

The form Lucas’ is commonly used in AP Style, which is preferred in journalism and some forms of professional writing. In this case, you simply add an apostrophe at the end of the name without an additional “s.”

• Example sentence: Lucas’ family is planning a surprise party for him.

Here, the apostrophe shows that the family belongs to Lucas, but the additional “s” is dropped, which is common in AP Style.
