Since vs After (What’s the Difference?)

When distinguishing between “since” and “after,” it’s essential to recognize that both terms relate to time but are used differently. “Since” refers to a point in time from which something has been continuously happening or true, often used to denote the start of a duration.

In contrast, “after” indicates a sequence, specifying that one event occurs following another. This fundamental difference shapes their usage in language, as “since” often connects to ongoing conditions or changes since a specific moment, while “after” sets the order of events without implying duration.

Definition of Since

Since is a preposition, conjunction, or adverb that refers to a point in time from when an action started or a condition began and continues to the present. It is often used to express a duration of time up to now.

Usage and Examples of Since

  1. Temporal Usage (as a preposition): Refers to the time that has elapsed since a certain point.
    • Example: “I have been working here since 2010.”
  2. Causal Usage (as a conjunction): Used to explain a reason or cause.
    • Example: “Since you are not ready, we will leave without you.”
  3. Conditional Usage (less common, as a conjunction): Similar to “if.”
    • Example: “Since it might rain, take an umbrella.”

Definition of After

After is a preposition, conjunction, or adverb that indicates something happening subsequent to a particular event or time. It strictly relates to the sequence of events rather than duration.

Usage and Examples of After

  1. Temporal Usage (as a preposition): Describes something occurring later than something else.
    • Example: “After the movie, we went to dinner.”
  2. Conjunctional Usage: Introduces a clause that describes what happens following an event.
    • Example: “After she finished her work, she went for a walk.”
  3. Adverbial Usage: To indicate later time or behind.
    • Example: “He arrived shortly after.”
