The phrases "the way that she smiles" and "the way she smiles" are very similar in meaning and convey a similar idea, but there is a subtle difference in their structure.
"The way she smiles" is a more streamlined and commonly used construction. It directly describes the manner in which she smiles. This version is concise and flows smoothly in conversation.
"The way that she smiles" adds the conjunction "that" before "she smiles." While still conveying the same meaning, this version is slightly more formal or might feel a bit more deliberate in its presentation.
In essence, both phrases describe how someone smiles, but "the way she smiles" is generally preferred in casual conversation or writing, while "the way that she smiles" might be used in more formal contexts. The difference between them is not very significant, and you can choose the one that fits the tone and style you are aiming for.
I hope this helped!
