Learn Spanish (Latin America): Como el frío es intenso, lo posponemos. - Since the cold is intense, we are postponing it.

When como is placed at the very beginning of a sentence to introduce a reason, it means 'since' or 'because'. It sets up the cause (el frío es intenso) before telling us the result (lo posponemos). Notice that it does not have an accent mark; cómo with an accent means 'how'.

Could I start this sentence with porque instead of como?

Usually, no. In Spanish, it sounds much more natural to use como when starting a sentence with a reason. You will rarely hear a statement start with porque unless it is answering a direct question. If you want to use porque, you should flip the order: Lo posponemos porque el frío es intenso.

Why use es instead of está? Isn't weather temporary?

While we often use hacer for weather (like hace frío) or estar for conditions (está nublado), in this sentence el frío (the cold) is a noun. We are describing a characteristic of that noun. Because 'intense' is the defining quality of the cold we are experiencing, we use the verb ser (es).

Why is lo before the verb in lo posponemos?
