Ludwig's WRAP-UP
The phrase "at which index" serves to specify a location within a numerically indexed sequence. Ludwig AI indicates that while grammatically correct, the phrase appears infrequently, particularly in formal and scientific contexts. When employing this phrase, clarity is paramount: ensure that the context necessitates the precision of a numerically indexed position and that alternatives like "at what position" or "at what location" are not more appropriate. Although the usage examples are scarce, understanding its grammatical function and typical contexts ensures effective and accurate communication.
