Writing well

Ceylon Medical Journal, 2000; 45: 49-51

To write for doctors about the art of writing might appear presumptuous or be thought foolhardy. Don't the diplomas and degrees we have got by dint of bard work confer on us the ability to teach, examine and write well, in addition to the ability to doctor well? Perhaps they do. One thing is certain. Neither superb school­teachers nor excellent writers claim to be able, for example, to perform any surgi­cal operations or manage patients in intensive care units. Anyone who writes about how to write well runs the risk of having his or her writing examined critically and minutely. But writing about the art of writing seems no more risky than making a speech about the art of lecturing. Some risks have to be taken. It might be least hazardous to start with punctuation.

Stops
Periods, question marks and exclamation points are the end of sentence punctuation marks. Their use is usually straight-forward. The exercise of commas, semicolons, colons and dashes generates more contention. They are sops used within a sentence to signal "a break or pause in thought, to set off material or to introduce a new but connected thought"(1). Commas are the weakest of the three are the and colons the most forceful.

Stops have a 'grammatical' duty as well as a 'rhetorical' one. The former has to do with construction of a sentence eg.
1 The rash which had been present for a week, disappeared quickly after prednisolone therapy.
2 I am compelled, however reluctantly, to impose this punishment.

The 'rhetorical' duty is to introduce shades of meaning, as illustrated by the following pairs of sentences.

3 He was apparently willing to support you.
4 He was, apparently, willing to support you.
5 I went to Manel's house and I found him there.
6 I went to Manel's house, and I found him there.

The fourth sentence above contains a hint of doubt about his bona fides lacking in the previous one. The fifth is a bland statement, whereas the sixth conveys a small element of surprise.

Two other general observations on the use of stops are worth remembering. Taste and common sense are more important than any rules; you put in your stops to help your readers to understand you, not to please grammarians. And you should write in such a way that they will understand you with a minimum of help of that sort" (2). "It is a sound principle that as few stops should be used as will do the work. Everyone should make up his mind not to depend on his stops" (3).

Comma

The contemporary fashion is to use few commas, but fashions vary from time to time; and good writers of a given period may disagree among themselves about tradition. One authority asserts: There are definite rules for using commas" (1). Another boldly declares: "The use of commas cannot be learned by rule" (2). It would be obviously futile here to take sides. The writer is safe who follows current convention and uses commas only when a pause or break is re­quired to avert ambiguity, confusion or untidiness in diction. As with most other matters pertaining to style, right and wrong use of commas is best illustrated by examples.

(a)  Commas are appropriate for enclosing parenthetical words, phrases or other expressions that interrupt the flow of a sentence eg. after all, on the other hand, of course, therefore, moreover, however etc

7 The real problem. of course, is to obtain uncontaminated specimens of urine.
8  The wisest thing to do, unless the biopsy report is conclusive, is to withhold fluorouracil therapy.
9 However, radioiodine uptake by the gland did not support a diagnosis of Graves' disease.
10 The battered-child syndrome, the clinical signs of which are often hard to detect, is an important consideration in this case.

(b) Use a comma before a conjunction (eg and, but, or, for, so, yet) introducing an independent clause.
11 The fever settled, but the ESR remained very high.
12 Cheek the blood glucose level if you are in doubt, for hypoglycaemia is a great deceiver If both clauses are short, a comma may be omitted.
13 This test is reliable but very expensive.
14 I have Bright's disease and he has mine. [S J Perelman, quoted in reference(1)].
15 Nero fiddled while Rome burnt.

(c) In a series of three or more items or terms with a single conjunction, use a comma after each, excepting the penultimate one. This comma is often called the 'serial' comma.

16 The hospital has specialists in surgery, medicine, paediatrics and anaesthesiology.
17 We catheterised the patient under anaesthesia, irri­gated his bladder and started him on intravenous gentamicin.

With the serial comma, accepted practice varies. Some authorities favour a comma between the penultimate item (or term) and the conjunction (sentences 18 and 19). But a writer must be consistent about the use of the serial comma. Do not use both conventions in a single article. Journals prefer one or the other, but they have to be consistent, too. 

18 The patient's blood was examined for urea, electrolyte, and glucose content.
19 Chest physiotherapy, broad-spectrum antibiotics, and maintaining fluid balance are critically important In such cases.

However, a comma is unnecessary if there are only two modifiers (sentence 20), or in a series of three or more modifiers, if they are seen as one term or entry (sentences 2land 22).

20 The appropnate test would be a randomised double-blind clinical trial.
21 We studied only Sri Lankan gaeriatric haemodialysis patients.
22 These patients had progressive chronic renal failure.
