When we talk about things that are internal, we are talking about what is happening on the inside. Think of an apple: the skin is the outside, but the juicy fruit you eat is the internal part.
In a business setting, internal communication refers to emails or memos sent only between employees, not to the public. It is all about what stays inside the group or the structure.
You can also use this word for people! Internal feelings are the ones you keep to yourself, rather than showing them to the whole world. It is a very versatile word for anything that isn't on the surface.
The word internal comes from the Latin word internus, which literally means 'inward' or 'inside'. It has been part of the English language since the 15th century.
It evolved from the Latin inter, meaning 'between' or 'among'. This is the same root we see in words like international, which means between nations.
Historically, it was used mostly in medical contexts to describe organs inside the body. Over time, it expanded to describe everything from company policies to computer hardware.
You will hear internal used in many professional settings. Common phrases include internal audit, internal medicine, and internal affairs.
It is generally considered a neutral or formal word. You wouldn't usually use it in casual slang; instead, you might just say 'inside'.
Use it when you want to sound precise about boundaries. If you are talking about a company, internal processes are the ones that keep the business running behind the scenes.
While 'internal' is a technical word, it appears in many concepts:
- Internal monologue: The voice in your head.
- Internal clock: Your body's natural rhythm for sleeping and waking.
- Internal combustion: How a car engine burns fuel inside.
- Internal strife: Fighting within a group or country.
- Internalize a problem: To keep your worries inside instead of talking about them.
The word internal is an adjective, so it usually comes before a noun (e.g., internal structure). It is not a countable noun, so you don't pluralize it.
The IPA pronunciation is /ɪnˈtɜːrnəl/. The stress is on the second syllable: in-TER-nal.
It rhymes with eternal, paternal, maternal, fraternal, and infernal. Keep that rhythm in mind to sound more natural!
