Which sentence has the correct word order? I've been already here two days. __ I've already been here two days. __ I've been here already two days.

## Step 1
The problem is about the correct word order in English sentences. The word order in English sentences typically follows the Subject-Verb-Object (SVO) pattern. However, when we have an adverb of time, such as "already", it usually goes before the main verb.
## Step 2
In the given sentences, the main verb is "been". The adverb "already" should be placed before this verb.
## Step 3
Looking at the options, only the sentence "I've already been here two days." follows the correct word order. The adverb "already" is placed before the main verb "been", which is the correct placement according to English grammar rules.
