This is likely influenced by the Spanish word domingo. The Malay word is minggu, from the Portuguese domingo.
The word linggo can mean ‘Sunday’ or ‘week.’
(To compare, the Spanish word for ‘week’ is semana.)
katapusan ng linggo
end of the week
last days of the week
There is no direct equivalent for the English word ‘weekend’ in Tagalog. The phrase katapusan ng linggo cannot be substituted for the English word ‘weekend.’ You have to specify which day you’re referring to.
Let’s meet on Saturday.
Nakita kita noong nakaraang Linggo.
I saw you last Sunday.
