Fewer or less when shopping? Compare bottles, amounts and prices in English

The BBC's lesson on less and fewer gives the usual distinction: fewer goes with plural countable nouns; less goes with uncountable nouns.

In a shopping conversation, compare these pairs:

Count separate things	Talk about an amount
fewer bottles	less juice
fewer bags	less rice
fewer loaves	less bread
fewer purchases	less shopping

The packaging does not determine the word for the contents. You can count bags of rice, but in "less rice," rice is being treated as an amount. Likewise, "fewer pieces of bread" counts pieces, while "less bread" describes a quantity without counting pieces.

Try saying the noun before building your comparison: "Bottles. We bought fewer bottles." Then change the noun: "Juice. Did we actually buy less juice?"

Here are two fictional baskets. The numbers are for language practice, not real prices or shopping advice.

Basket	Bottles	Size of each bottle	Total juice	Total paid
A	4	250 ml	1 litre	$8
B	2	750 ml	1.5 litres	$9

Compare B with A:

• B has fewer bottles: two instead of four.
• B has more juice: one and a half litres instead of one litre.
• The buyer spent more money on B: nine dollars instead of eight.

Now compare A with B: "A has more bottles, but less juice. It also costs less."

Neither "fewer bottles" nor "less juice" tells you the price by itself. You need the price information to make that comparison. And if you hear "We bought less this time," you still do not know whether the speaker means fewer items, a smaller total amount, or less of a particular food.

A useful spoken version is: "We bought fewer bottles, but they were bigger, so we got more juice."

You may wonder why people say "less than ten dollars" if dollars can be counted.

The Canadian Translation Bureau's guidance on fewer and less explains that less can accompany plural measurement units when the meaning is an overall amount, including money, distance and time.

For example:

• "I spent less than ten dollars" describes the total amount spent.
• "There are fewer coins in my pocket" counts separate coins.
• "We waited less than twenty minutes" describes a duration.

For these comparisons, look beyond whether the next word ends in s. Ask what the phrase measures. "Fewer coins" and "less money" can both be correct, but they do not necessarily describe the same change. One higher-value coin can be worth more than several smaller ones.

You can also avoid the measurement issue when you do not need a number: "It cost less than last time."

Imagine someone says, "Get less milk this time." That might mean a smaller total volume. It does not tell you whether to buy fewer cartons or smaller cartons.

Ask a short clarification:

"Do you mean fewer cartons, or smaller ones?"

If the answer is "We only need one litre altogether," you now have the quantity that matters. Repeat it: "One litre in total. Got it."

Similarly, "Buy fewer apples" is a request about number. "Buy less fruit" leaves the individual items open. You could ask, "Which fruit should I leave off the list?" rather than guessing that every item needs reducing.

The goal is not to correct the other person's grammar. It is to make sure you both mean the same change.

Use the two baskets above. One person reads the full table; the other sees only the bottle counts.

The listener starts: "B has fewer bottles, so does it have less juice?" The person with the full table answers using the sizes and totals. Then the listener asks whether B costs less. Check the money column separately.

Swap roles and invent another pair of baskets. Keep the calculations simple enough to check. Make the basket with fewer packages contain more of the food at least once, so the answer cannot come from the package count alone.

Finish by giving a summary without looking: "We compared the number of bottles, the amount of juice and the total price. B had fewer bottles, but more juice and a higher total price."

If practising alone, cover the totals, say your comparison aloud, then uncover them. Check the information as well as the grammar. A perfectly formed sentence can still describe the wrong basket.
