I heard this today on television.

Problem:
This is a nonsense word.

Explanation:
The “pre” in “pre-planning” is redundant, just as the “back” in “reply back” is redundant.

To plan something is to do think about something before it occurs.

The “pre” prefix also means before.

It makes no sense to think about something before before.

For fun, I searched Google for each of the following words (with the quotation marks) and got about the indicated numbers of matches:

• “planning” — 51,700,000 matches
• “pre-planning” — 890,000 matches

This tells me that Web authors have avoided this “pre-” redundancy by a ratio of 58.1:1, which is okay but not very good, especially in light of nearly one million(!) “pre-planning” matches.

Solution:
“Planning”
