Termbase Basics

Termbases help ensure consistent terminology across your translations.

What is a Termbase?

A termbase is a database of terms with their translations:

Source (EN)	Target (NL)	Domain	Notes
software	software	IT	Don’t translate
click	klikken	IT	Verb
machine learning	machinaal leren	AI	Official term

Why Use Termbases?

Consistency: Same term = same translation every time
Efficiency: Don’t look up the same term twice
Quality: Use approved terminology
Client requirements: Follow style guides

Termbase Features in Supervertaler

Automatic Highlighting

Terms from termbases with Read ticked are highlighted in the source text:

Semibold green text by default (a pastel green background or a dotted underline are the alternatives)
Hover to see the translation
Terms from the project termbase are a darker green than those from background termbases
Forbidden terms are marked differently (dark red text in the default style)

Multiple Termbases

Maintain separate termbases for:

Different clients
Different domains (legal, medical, IT)
Different projects

Project and Background Termbases

Each project has one Project termbase – the highest-priority one, marked 📌 Project and shown in pink in the Termbases tab and in TermLens. Tick the Project column in the 🏷️ Termbases tab to make a termbase the project termbase. All other termbases with Read ticked are Background termbases.

The two quick-add shortcuts follow the same split: Alt+Up adds the selected term pair to the project termbase, Alt+Down to the first background termbase with Write ticked.

Forbidden and Non-Translatable Terms

Tick Forbidden on a term to flag a translation that must not be used. Forbidden terms are marked in the grid and in TermLens, and the AI is told not to use them.
To keep a word untranslated (a brand or product name, say), tick Non-translatable (keep source text in target) in the term entry editor instead, or use 🚫 Add to Non-Translatables (Ctrl+Alt+N) from the right-click menu.
