Ludwig's WRAP-UP
In summary, the phrase "first or later" is used to denote a choice in timing, allowing for an action to be done immediately or deferred. While grammatically acceptable, it is not the most common or precise way to express this idea, as noted by Ludwig. It appears primarily in scientific and news contexts and might benefit from clearer alternatives like "initially or subsequently" for improved clarity and formality. Therefore, while understandable, using more specific language is generally recommended.
