Here's why:
* Prepositional Phrases: These are groups of words that begin with a preposition (like "in," "on," "at," "with," "by," etc.) and end with a noun or pronoun (the object of the preposition).
* In this example: "in" is the preposition, and "his loving manner" is the object of the preposition.
While the phrase itself suggests a positive and affectionate quality, the term describing its grammatical structure is a prepositional phrase.
