What's an example of a 'cheville' word in english?

The dictionary.com word of the day is 'Cheville' and it explains it as such: A word or expression whose only function is to fill a metrical gap in a verse or to balance a sentence.

Can anyone give some examples of these words?

Solution 1:

One possible example is noted in this sonnet (the "Oh," in line 5)

I am in need of music that would flow
Over my fretful, feeling finger-tips,
Over my bitter-tainted, trembling lips,
With melody, deep, clear, and liquid-slow.
Oh, for the healing swaying, old and low,
...

Source: Sonnet (1928) by Elizabeth Bishop

In addition, the insertion of "dost" (or "do") in order to match the meter requirements is another example:

How can my Muse want subject to invent,
While thou dost breathe, that pour'st into my verse

Source: Sonnet 38 by Shakespeare

Solution 2:

Most intensifiers - "very", "quite", "so", etc. - add no real meaning, and can be added or dropped at will to assist in scansion.

In addition, declamatory introductions such as "Oh", "Lo", etc. can fill the same role; they're a bit less common in modern usage, however.

Solution 3:

Stated, the normal usage is in verse/lyrical sense

So in the modern age a more appropriate 'Cheville' example would be:

(no cheville) you know how it feels when the car has no wheels

(Cheville) you know how it - really feels when your car 'ain't got' no wheels

It has no real obvious purpose other then enforce, empower and/or change the lyrical flow of the verse to match maybe a beat and/or compensate for missing "glue" to match the previous statement/rhyme.
