person in a job before someone
A person who had a job or position before another person in the same job or position.
用法パターン：
[someone]'s predecessor in [a job/role]

Learners sometimes confuse "predecessor" with "successor". Remember: a predecessor comes before you in a job or role, and a successor comes after you. Some learners also use it only for things, but it is very commonly used for people in positions.

former holder (Neutral description; less formal and more explicit than "predecessor".)

forerunner (More general or sometimes literary; can sound a bit more dramatic or historical.)

earlier version of a thing
A product, machine, system, or other thing that was used before the one we have now.
用法パターン：
the predecessor of [a thing]
よくある間違い：
Learners sometimes think "predecessor" is only for people. It is also common for machines, products, systems, and policies. Another mistake is saying *"the predecessor phone of this"*; more natural is *"this phone's predecessor"* or *"the predecessor of this phone"*.
類義語
previous version (More informal and plain; clearly refers to an earlier form of the same thing.)
|
forerunner (Often suggests an earlier form that led to or influenced the current one; slightly more literary.)

earlier person in your family line
A person in your family who lived before your grandparents and from whom you come, used in formal or historical writing.
用法パターン：
a predecessor of [a person/family/line]
よくある間違い：
Learners may use "predecessor" instead of the more common word "ancestor" when talking about family history. "Predecessor" sounds more formal or academic and is used more often for jobs or systems than for family members.
類義語
ancestor (More common and direct word specifically for earlier family members.)
|
forebear (Formal or literary; clearly refers to family ancestors.)
対義語
descendant (Names the people who come after someone in a family line, opposite in time direction.)
