Best practice
Always ensure subject-verb agreement. When referring to multiple periods, use the plural form "periods". When referring to a singular period, use "this period".
Common error
Avoid using the singular noun "period" with the demonstrative adjective "these", which is plural. This leads to grammatical errors. Always check number agreement between demonstrative adjectives and nouns.

Ludwig's WRAP-UP
The phrase "during these period" is grammatically incorrect. The correct forms are "during this period" (singular) or "during these periods" (plural). Ludwig AI emphasizes that accuracy in grammar is crucial for clear communication. While the phrase attempts to provide temporal context, its incorrect form undermines its effectiveness. Ludwig's analysis of usage patterns shows it appearing in a mix of scientific and general contexts, but its rarity suggests caution in formal writing. Alternatives like "throughout these periods" or "in these timeframes" can offer grammatically sound substitutes depending on the specific meaning you wish to convey. Always ensure number agreement between demonstrative adjectives and nouns.
