## Overview

Build an acronym or initialism from a phrase — pick which words contribute a letter, which letter(s) to take, how to join them, and the final case.

**Word source — which words contribute:**
- **Each word** — every word in the phrase gives a letter. `National Aeronautics and Space Administration` → `NASA` (one letter per word).
- **Capitalized words only** — only words that start with a capital letter contribute. Great for extracting the meaningful nouns out of a title while skipping small filler words. `National Aeronautics and Space Administration` → `NASA` (the lowercase "and" is skipped automatically).

**Letter from — which letter(s) each contributing word gives:**
- **First letter** — the usual initialism behavior: take the first character.
- **First + last letter** — take both the first and last character of each word. `cat` → `CA`. Fun for stylized brand acronyms and puzzles.

**Separator & case:**
- **Separator**: none (`NASA`), period (`N.A.S.A`), hyphen (`N-A-S-A`), or space (`N A S A`).
- **Case**: uppercase (default) or lowercase.

**Good to know:**
- A "word" is any run of letters; numbers and punctuation are treated as separators and don't contribute letters of their own.
- With "First + last letter" mode, single-letter words contribute just that one letter (no doubling).

## Inputs

- **Text** (textarea): Enter a phrase to turn into an acronym, e.g. "National Aeronautics and Space Administration"...
- **Word source** (select)
- **Letter from** (select)
- **Separator** (select)
- **Case** (select)

## When to use

- When naming a new software project, internal initiative, or organization and you need a catchy, memorable codename or abbreviation.
- When extracting core initials from long titles or academic phrases while automatically filtering out lowercase filler words like 'and' or 'of'.
- When designing stylized brand names, puzzles, or unique identifiers that require combining the first and last letters of words.

## How it works

- Enter the full phrase or title you want to abbreviate into the text input area.
- Select your word source preference to either include every word or filter for capitalized words only.
- Choose whether to extract just the first letter or both the first and last letters of each contributing word.
- Set your preferred separator (none, period, hyphen, or space) and output case (uppercase or lowercase) to generate the final acronym.

## Use cases

- Creating official organizational initialisms from long agency titles.
- Generating unique project codenames and product abbreviations for development teams.
- Designing stylized brand names and word puzzles using first-and-last letter combinations.

## Frequently asked questions

### How does the generator handle small filler words like 'and' or 'the'?

You can skip them automatically by setting the Word Source option to 'Capitalized words only', which ignores lowercase words.

### Can I generate acronyms with periods or hyphens between the letters?

Yes, you can choose between no separator, periods, hyphens, or spaces to format your output.

### What happens to numbers and punctuation in the input phrase?

Numbers and punctuation are treated as word separators and do not contribute letters to the final acronym.

### How does the 'First + last letter' option handle single-letter words?

Single-letter words will only contribute that single letter once, preventing any character doubling.

### Can I output the acronym in lowercase?

Yes, the tool allows you to toggle the case mode between uppercase and lowercase.
