  • Temporal Connotations: Over time, the term since retained its temporal connotations but also acquired causal implications. It signifies a point in time from which a situation, action, or state has continued or originated.
  • Causal Usage: In addition to temporal connotations, since is used to introduce reasons or explanations for actions or states. It indicates a cause-effect relationship, emphasizing the reason or condition that has led to a particular outcome.
  • Contemporary Usage: In modern English, since is a versatile word used in various contexts to denote temporal succession or causation. It is commonly employed in both spoken and written language to provide clarity and coherence in expressing temporal and causal relationships.

From its origins in Old English to its contemporary usage, the term since embodies the intertwining of temporal and causal concepts, enriching language with its nuanced expression of temporal succession and causation.
