##### **Example - Adjectives:**

##### **<mark>SLOW (adj) (SLOWER, SLOWEST)</mark>**

This word tells you that you can use the approved adjective “slow” as follows:

|Base form|Comparative form|Superlative form|
|---|---|---|
|Slow|Slower|Slowest|

Adjectives that make their comparative and superlative forms with “more” and “most” do not have these forms in the dictionary. This is because “more” and “most” are approved words.

### **Technical nouns**

**Rule 1.5 You can use words that you can include in a technical noun category.**

A technical noun is a noun term that refers to a specified concept and is applicable to a subject field.

The dictionary does not include technical nouns because there are too many, and each subject field uses different technical nouns for their texts.

You can find many of these technical nouns in your company glossary or terminology database. STE gives you a list of categories, with examples, to help you:

- Select technical nouns to put in your company glossary or terminology database.

- Use technical nouns correctly.

You can use technical nouns in procedural and descriptive writing if you can include them in one or more of these twenty-two categories.

##### **1. Official parts information**

- Terms that refer to all design items. For example, technical nouns included in illustrated parts catalogs or engineering drawings.
