side remark

Let me make a perhaps slightly confusing side remark.

As is often the case, there was an unscripted side remark when he hit a particularly vivid passage.

Yes, it was a hearty good-bye to all outward appearance, but there was a lump in Leonard’s throat all the same that he had a good deal of difficulty in swallowing; and as soon as the Fairy Queen was out of sight, the two fathers had left the pier—not side by side, remark we, but one in front of the other, Indian-file fashion.

As a side remark, English and French are the only official and/or cultural languages widely spread on five continents.

"Are you sure?" said Gibbs, mildly; "for I have noticed several times when you have seemed not to hear a side remark."
