Article Rules (the #1 giveaway for non-native speakers)
- a/an = any one of many ("a meeting", "an idea")
- the = specific one we both know about ("the deck I sent", "the deal")
- no article = general concept ("data is valuable", "money talks")
Sentence Surgery - Before & After
Before: "Taking into account the current market conditions and the fact that our competitors are already offering similar solutions, we have decided to accelerate the timeline for the delivery of the first batch of data." After: "Market's moving fast. Competitors already have similar offerings. We're accelerating delivery of the first batch." Rule: One idea per sentence. Context first only if absolutely needed.
Before: "I wanted to ask you whether it would be possible for us to schedule a meeting sometime next week in order to discuss the details of the proposal." After: "Can we meet next week to go over the proposal?" Rule: 12 words. Don't ask permission to ask a question.
Before: "As for the pricing, we are currently in the process of evaluating different options and will get back to you as soon as we have finalized our approach." After: "Still working on pricing. Will have numbers for you by Friday." Rule: Cut "as for", "in the process of", "as soon as". Just say when.
