movement of people between places
When many people move from one place to another place to live or work there.
Μοτίβο χρήσης:
migration of [people] from [place] to [place]
Συχνό λάθος:
Learners often confuse 'migration', 'immigration', and 'emigration'. 'Migration' is the general word for moving from one place to another. 'Immigration' is entering a new country to live there. 'Emigration' is leaving your own country to live in another. Many learners also use it incorrectly as a verb (*people migration to cities*); the correct forms are 'people migrate' (verb) or 'there is migration' (noun).
Συνώνυμα
relocation (Usually refers to individuals or smaller groups and sounds more personal or business-related, less about large population movements.)
|
population movement (More technical and descriptive; focuses on changes in where people live without the legal or political associations of 'migration'.)
|
immigration (Focuses on people entering a country; 'migration' is broader and includes movement within a country and leaving a country.)
Αντώνυμα
settlement (Describes people staying and establishing homes in one place, the opposite of moving away.)

seasonal movement of animals
When animals move to another place at certain times of the year and then come back.
Μοτίβο χρήσης:
migration of [animals] between [place] and [place]
Συχνό λάθος:
Learners sometimes think 'migration' here means any short movement. In biology, it usually describes long-distance, often seasonal travel between areas, not everyday movement within a small area.
Συνώνυμα
seasonal movement (A more descriptive phrase that makes the regular timing clear but is less specific to animals.)
|
animal movement (Very general and does not imply regular or long-distance travel the way 'migration' does.)
Αντώνυμα
sedentariness (Describes animals (or groups) that stay in one place instead of moving regularly between areas.)

moving data or systems in IT
The planned move of computer data or programs from one system or place to another.
Μοτίβο χρήσης:
migration of [data/systems] from [system] to [system]
Συχνό λάθος:
Some learners use 'migration' instead of 'update' or 'upgrade' (e.g. *software migration* when they only mean installing a new version on the same system). In IT, 'migration' usually means moving to a different system, platform, or storage environment, not just updating a program.
Συνώνυμα
transfer (A more general term for moving data; it does not always include the careful planning and technical changes implied by 'migration'.)
|
transition (Focuses on the overall change from one system to another, not only on the movement of data.)
Αντώνυμα
retention (Emphasizes keeping data or systems in their current location or form instead of moving them.)

movement of cells or particles
In science, the way small things like cells or chemicals move through another material.
Μοτίβο χρήσης:
migration of [cells/particles/chemicals] through [medium]
Συνώνυμα
movement (A very general term; 'migration' in this sense is used in more technical, measured contexts.)
|
diffusion (A specific physical process; sometimes related but not identical, as 'migration' may involve directed or driven movement, not only random spreading.)
