Ways to tell them apart:

etymology
  • Replicate often suggests making a copy or reproduction of something, usually in exact terms. For instance, duplicates might vary slightly, but replicates are expected to be identical or as close as possible.
  • Duplicate is more about having another one of something, implying two or more identical copies, but there can be minor acceptable differences in casual usage.
  • Think of replicate in scientific terms, like replicating an experiment, where precision is key, whereas duplicate can be as simple as making another photocopy of a document.
  • Replicates often have a connotation of effort or intention to match something precisely, like in art or research, while duplicate is often more about convenience or necessity, such as a spare key.
  • In biological terms, replication occurs in DNA where the focus is on creating an accurate copy, whereas duplication might be more related to redundant or spare copies.
