book or app for planning time
A book or app where you write your plans, meetings, and things to do.
用法パターン：
a(n) [daily/personal] organizer for [appointments/tasks]
よくある間違い：
Learners sometimes confuse *organizer* (the book or app) with *organization* (a group or company). Example error: *I wrote it in my organization.* Correct: *I wrote it in my organizer.* Also, *organizer* in this sense is a countable noun and usually needs an article: *I bought an organizer*, not *I bought organizer.*
類義語
planner (Most common everyday word; often interchangeable, sometimes slightly more general.)
|
diary (In British English, can mean a datebook; in other contexts, suggests a record of personal thoughts.)
|
agenda (Can mean a list of items for meetings; less often used for a full personal planning book or app.)
対義語
scrap of paper (Represents a very unstructured way of keeping notes and plans, opposite to a dedicated organizer.)

container with sections for items
A box or tool with many parts that helps you keep things neat and in order.
用法パターン：
a(n) [drawer/desk/closet] organizer for [items]
よくある間違い：
Learners may think *organizer* always means a person. In sentences like *I bought a desk organizer*, *organizer* is an object, not a person. Context and the words before it (like *desk*, *drawer*, *closet*) show that it is a thing.
類義語
storage container (General; does not always suggest separate sections or focus on order.)
|
divider (Focuses on the parts that separate space; may not hold items by itself.)
|
caddy (Informal term for a small container you carry that holds several items, often on a handle.)
対義語
pile (Suggests things are stacked or heaped without any order or structure.)
|
mess (General word for a very disorganized collection of items.)

embryonic region guiding development
In biology, a small part of a young animal or plant that tells nearby cells how to grow and form body parts.
用法パターン：
the [embryonic/Spemann] organizer in [species]
よくある間違い：
Non-specialists may assume this is the same as a person who organizes things. In biology texts, *organizer* refers to a group of cells, not a human role.
類義語
inductive center (Technical term stressing its role in sending signals that cause other cells to change.)
対義語
responding tissue (Refers to cells that receive instructions rather than organize development; opposite role in the process.)
