Frequently Asked Questions
What is a portmanteau word?
A portmanteau is a new word created by blending two existing words — taking the beginning of one and the end of another (or overlapping shared sounds). 'Brunch' (breakfast + lunch) and 'smog' (smoke + fog) are classic examples.
How does the blending algorithm work?
The tool tries every possible split point for both words and combines them into candidate blends. Each blend is scored based on balance (roughly equal contributions from each word), phonetic overlap (shared letters at the join point), and ideal length (5–9 characters).
What does the blend score mean?
The blend score (0–100) indicates how natural and well-formed a portmanteau sounds. Higher scores mean the blend is more balanced, phonetically smooth, and an appropriate length.
