seventy

'Seventy' is a cardinal number representing the quantity of 70. It's a fundamental number used in counting, measuring, and expressing quantities in everyday life. As an A2 level word, it's expected that learners can recognize and use it in basic contexts.

'Seventy' is primarily used as a standalone number to denote quantity, as in 'There were seventy people at the party.' It can also be used in combination with other numbers, especially when forming larger numbers (e.g., 'seventy-five'). It's commonly used when discussing age, time, money, measurements, and scores.

• Age: 'She is seventy years old.'

• Time: 'The meeting is scheduled for seventy minutes.' (though less common than specific hours/minutes)

• Money: 'The item costs seventy dollars.'

• Measurements: 'The speed limit is seventy miles per hour.'

• Scores: 'The final score was seventy to sixty.'

• Seven: This is the base digit (7). 'Seventy' is seven tens (7 x 10 = 70).

• Seventeen: This is a distinct number between ten and twenty (17). It does not follow the 'tens' pattern of 'seventy'.

• Seventieth: This is an ordinal number, referring to the position in a sequence (the 70th item), not the quantity itself.
