Questions & Answers about El documento estipula un pago mensual, o sea, pagas cada mes.
Can I use es decir or esto es instead of o sea in this sentence?
Yes, they are interchangeable here. o sea and es decir are used to clarify or rephrase the previous statement to mean "in other words" or "that is to say". o sea is very common in everyday spoken Spanish, while es decir is slightly more formal, and esto es is the most formal, usually found in writing.
Since sea is a subjunctive verb, does it force the next verb into the subjunctive too?
No. While o sea originally comes from the subjunctive of ser (meaning "or it may be"), it functions today as a fixed connector. It doesn't govern the verbs that follow it. Because you are stating a fact about the payment, the following verb stays in the indicative mood (pagas).
Are the commas around o sea mandatory?
I've seen people online write this as a single word (osea). Is that a valid alternative?
No, writing it as one word is a very common spelling error, even among native speakers. When used as a connector meaning "in other words", it must always be two words: o sea. If you see it written as a single word with an accent (ósea), it is an adjective meaning "bony" or "relating to bones".
