Always make sure that each item in the vertical list connects clearly and correctly to the first part of the vertical list (the text that is before the colon).

##### **Example:**

|_Non-STE:|_Do not use acetone for cleaning these parts after the repair:_<br>-<br>_the service cabinet,_|
|---|---|
||-<br>_the toilet shrouds with the supports,_<br>-<br>_parts made of polycarbonate._|
|STE:|After the repair, do not use acetone to clean:<br>-<br>The service cabinet<br>-<br>The toilet shrouds|
||-<br>The toilet shroud supports|
||-<br>Parts made of polycarbonate.|

Always make sure that the layout of your vertical list is easy to read. In the example that follows, there is a second vertical list included in the primary vertical list. Use the same level for all items in the vertical list.

##### **Example:**

|_Non-STE:|_Remove these parts:_<br>- _The four screws (3)_<br>- _The four washers (4)_<br>- _The flange (2) that includes:_<br>_- The two O-rings (6)_<br>_- The seals (7)_<br>- _The shims (8)_<br>- _The spring (9)._|
|---|---|
|STE:|Remove these parts:<br>- The four screws (3)<br>- The four washers (4)<br>- The flange (2) (that includes the two O-rings (6) and the seals (7))<br>- The shims (8)<br>- The spring (9).|

An item in a vertical list can contain a verb and not be a full sentence. Then, you do not use a period at the end of that item.

##### **Example:**

|_Non-STE:|_The middle part of the reservoir has the components that follow:_<br>- _One check valve that prevents the backflow of fluid._<br>- _One air relief valve that opens at a pressure of 25 psi._|
|---|---|
||- _One transfer pipe connected to the pressurization manifold._|
|STE:|The middle part of the reservoir has the components that follow:<br>-One check valve that prevents the backflow of fluid<br>-One air relief valve that opens at a pressure of 25 psi<br>-One transfer pipe connected to the pressurization manifold.|

### **Connecting words and connecting phrases**

#### **Rule 4.4 Use connecting words and connecting phrases to connect sentences that contain related topics.**

Connecting words and connecting phrases connect a topic in one sentence with an idea in a sentence that follows.

In a descriptive text, connecting words and connecting phrases give your writing a logical structure and give information that is easy to understand.

Some of the connecting words that are approved in the dictionary are "and," "but," "then," and "thus."

"As a result" and "at the same time" are examples of connecting phrases that you can use.

##### **Examples in STE:**

(Refer to the underlined connecting words and connecting phrases.)

The localizer course aligns with the centerline of the runway. And the glideslope path is at a constant angle to the threshold of the runway.

These safety precautions are the minimum necessary for work in the pit lane. But the local regulations can give other necessary safety precautions.

If the pressure increases, it changes the electrical currents in the transmitter. Thus, the power unit supplies currents to the indicator on the related panel.

When the hydraulic pressure is released, the sequence valve moves to the open position. <u>As a result, the actuators are connected to the hydraulic return.</u>

You can also use demonstrative adjectives as connecting words to connect ideas in related sentences.

In procedures, you can use these connecting words when an explanation is necessary after a work step. Connecting words can also be necessary in safety instructions to connect related sentences or make the text clear.

##### **Examples in STE:**

(Refer to underlined connecting words.)

<mark>Tag the disassembled parts.</mark> <u><mark>This method will help you during the subsequent procedures.</mark></u>

<u><mark>WARNING:</mark></u> <mark>ALWAYS USE PROTECTIVE EQUIPMENT IN THIS AREA. THIS PRECAUTION</mark> WILL PREVENT INJURY.

### **Articles and demonstrative adjectives**

#### **Rule 4.5 When applicable, use an article (the, a, an) or a demonstrative adjective (this, these) before a noun or a multi-word noun.**

Articles and demonstrative adjectives show the position of nouns and multi-word nouns in the sentence. Use articles and demonstrative adjectives correctly and do not omit them to make the text shorter.

##### **Examples:**

|_Non-STE:<br>STE:|_Turn shaft assembly.<br>Turntheshaft assembly._|
|---|---|
|_Non-STE:<br>STE:|_Data module tells you how to operate unit.<br>Thisdata module tells you how to operate the unit._|
|STE:|You can use equivalent alternatives fortheseitems.|

It is not always correct English to put an article before a noun. Do not use articles in general statements or concepts.

##### **Examples in STE:**

|STE:|Solventscan cause damage topaint.|
|---|---|
|||(No articles before "solvents" or "paint." The context does not give a specified<br>solvent or paint.)|
|STE:|The machine operates withhigh efficiency.|
|||(No article before "high efficiency." The sentence refers to a general concept.)|
|STE:|This software increasesperformance.|
|||(No article before "performance" because it refers to an abstract quality.)|

In short sentences, it can be clearer to use articles before all nouns.

<mark>STE: Install the nuts (2) and the bolts (3).</mark>

But sentences that contain a long series of items are clearer when you use the article only before the first noun in the series.

<mark>STE: Discard the O-rings (3), gaskets (4), seals (7), and washers (9).</mark>

When you use the article in a series of items, always make sure that adjectives do not cause ambiguity.

<mark>STE: Install the new O-rings (15), spacers (14), nut (13), and safety pin (12).</mark> (The article in this instruction tells you that all items in the series are new.)

<mark>STE: Install the new O-rings (15), the spacers (14), the nut (13), and the safety pin (12).</mark> (The articles in this instruction tell you that only the O-rings (15) are new.)

A definite article is incorrect before a noun when an alphanumeric identifier comes after it. This is because the alphanumeric identifier shows that it is a proper noun.

##### **Example:**

_<mark>Incorrect: Tag the circuit breaker 36L7</mark>_ <mark>. CORRECT: Tag circuit breaker 36L7.</mark>

<mark>If you are not sure about how to use the articles correctly in your writing, refer to a</mark> comprehensive grammar book, for example, "Practical English Usage" by Michael Swan. This type of resource gives clear explanations on grammar topics, which include how and when to use articles correctly in your text.
