Coherence Strategies: Signal Words and Phrases

By Richard Nordquist, About.com

Let's consider how signal words and phrases can help to make our writing clear and coherent.

As we've seen, a key quality of an effective paragraph is unity. A unified paragraph sticks to one topic from start to finish, with every sentence contributing to the central purpose and main idea of that paragraph.

But a strong paragraph is more than just a collection of loose sentences. Those sentences need to be clearly connected so that readers can follow along, recognizing how one detail leads to the next. A paragraph with clearly connected sentences is said to be coherent.

The following paragraph is both unified and coherent. As you read, notice how the italicized words and phrases (which we call signals) guide us along, helping us to see how one detail leads to the next.

Why I Don't Make My Bed


Ever since I moved into my own apartment last fall, I have gotten out of the habit of making my bed--except on Fridays, of course, when I change the sheets. Although some people may think that I am a slob, I have some sound reasons for breaking the bed-making habit. In the first place, I am not concerned about maintaining a tidy bedroom because no one except me ever ventures in there. If there is ever a fire inspection or a surprise date, I suppose I can dash in there to fluff up the pillow and slap on a spread. Otherwise, I am not bothered. In addition, I find nothing uncomfortable about crawling into a rumpled mass of sheets and blankets. On the contrary, I enjoy poking out a cozy space for myself before drifting off to sleep. Also, I think that a tightly made bed is downright uncomfortable: entering one makes me feel like a loaf of bread being wrapped and sealed. Finally, and most importantly, I think bed-making is an awful way to waste time in the morning. I would rather spend those precious minutes checking my email or feeding the cat than tucking in corners or snapping the spread.

Signal words and phrases guide readers from one sentence to the next. Although they often appear at the beginning of a sentence, they may also show up in the middle (usually after the subject) or even at the end. Here are the common signal words and phrases, grouped according to the type of relationship shown by each.



1. Addition Signals

    and
    also
    besides
    first, second, third
    in addition
    in the first place, in the second place, in the third place
    furthermore
    moreover
    to begin with, next, finally

    Example
    In the first place, no "burning" in the sense of combustion, as in the burning of wood, occurs in a volcano; moreover, volcanoes are not necessarily mountains; furthermore, the activity takes place not always at the summit but more commonly on the sides or flanks; and finally, the "smoke" is not smoke but condensed steam.
    (Fred Bullard, Volcanoes in History, in Theory, in Eruption)

2. Cause-Effect Signals

    accordingly
    and so
    as a result
    consequently
    for this reason
    hence
    so
    then
    therefore
    thus

    Example
    The ideologue is often brilliant. Consequently some of us distrust brilliance when we should distrust the ideologue.
    (Clifton Fadiman, “Eggheads, Intellectuals, Ideologues, Highbrows”)

3. Comparison Signals

    by the same token
    in like manner
    in the same way
    in similar fashion
    likewise
    similarly

    Example
    When you start with a portrait and search for a pure form, a clear volume, through successive eliminations, you arrive inevitably at the egg. Likewise, starting with the egg and following the same process in reverse, one finishes with the portrait.
    (Pablo Picasso)

4. Contrast Signals

    but
    however
    in contrast
    instead
    nevertheless
    on the contrary
    on the other hand
    still
    yet

    Example
    Every American, to the last man, lays claim to a “sense” of humor and guards it as his most significant spiritual trait, yet rejects humor as a contaminating element wherever found. America is a nation of comics and comedians; nevertheless, humor has no stature and is accepted only after the death of the perpetrator.
    (E. B. White)

5. Conclusion and Summary Signals

    and so
    after all
    at last
    finally
    in brief
    in closing
    in conclusion
    on the whole
    to conclude
    to summarize

    Example
    Reporters are not paid to operate in retrospect. Because when news begins to solidify into current events and finally harden into history, it is the stories we didn’t write, the questions we didn’t ask that prove far, far more damaging than the ones we did.
    (Anna Quindlen)

6. Example Signals

    as an example
    for example
    for instance
    specifically
    thus
    to illustrate

    Example
    With all the ingenuity involved in hiding delicacies on the body, this process automatically excludes certain foods. For example, a turkey sandwich is welcome, but the cumbersome cantaloupe is not.
    (Steve Martin, "How to Fold Soup")

7. Insistence Signals

    in fact
    indeed
    no
    yes

    Example
    The joy of giving is indeed a pleasure, especially when you get rid of something you don’t want.
    (Frank Butler, Going My Way)

8. Place Signals

    above
    alongside
    beneath
    beyond
    farther along
    in back
    in front
    nearby
    on top of
    to the left
    to the right
    under
    upon

    Example
    What did it matter where you lay once you were dead? In a dirty sump or in a marble tower on top of a high hill? You were dead, you were sleeping the big sleep, you were not bothered by things like that.
    (Raymond Chandler, The Big Sleep)

9. Restatement Signals

    in other words
    in short
    in simpler terms
    that is
    to put it differently
    to repeat

    Example
    Anthropologist Geoffrey Gorer studied the few peaceful human tribes and discovered one common characteristic: sex roles were not polarized. Differences of dress and occupation were at a minimum. Society in other words, was not using sexual blackmail as a way of getting women to do cheap labor, or men to be aggressive.
    (Gloria Steinem, "What It Would Be Like If Women Win")

10. Time Signals

    afterward
    at the same time
    currently
    earlier
    formerly
    immediately
    in the future
    in the meantime
    in the past
    later
    meanwhile
    previously
    simultaneously
    subsequently
    then
    until now

    Example
    At first a toy, then a mode of transportation for the rich, the automobile was designed as man's mechanical servant. Later it became part of the pattern of living.
