Understanding Signal Words and Tenses in English Grammar
The English language relies heavily on specific time indicators called signal words to help determine which tense to use. Understanding these signal words for simple past and present perfect is crucial for mastering English grammar and communication.
When using the simple past tense, specific time markers indicate completed actions in the past. Common signal words include yesterday, last week, last month, last year, and ago. For example, "I started my homework yesterday" clearly shows a finished action at a defined past moment. These signal words help establish the exact time frame when something occurred.
The present perfect tense uses different signal words to show actions that began in the past but have a connection to the present. Words like already, ever, since, for, and just indicate this tense. For instance, "I have already started my homework" suggests the action began previously but remains relevant now. These signal words help express duration, completion, or experience up to the present moment.
Definition: Signal words are specific time-related terms that help indicate which verb tense to use in English.
