The word ‘lastly’ is often debated among grammarians and writers. While it is commonly used to indicate the final point in a list or argument, some experts argue that it may not be the most elegant choice.
Traditionally, the preferred terms are ‘finally’ or ‘last’ when concluding an argument. ‘Finally’ conveys a sense of culmination and is more widely accepted in formal writing. In contrast, ‘lastly’ can sound somewhat awkward or stilted, especially in academic or professional contexts.
However, it is not incorrect per se. Language is fluid, and usage can vary based on context and audience. In informal writing or speech, using ‘lastly’ might be perfectly acceptable. The key is to consider your audience and the tone of your writing.
In conclusion, while ‘lastly’ is recognized and can be used in English, opting for ‘finally’ or simply ‘last’ may serve you better in many settings.
