Siyokoy is a term coined by Virgilio Almario that refers to Filipino-language hybrid words seemingly derived from both English and Spanish.
[1] The Komisyon sa Wikang Filipino under the administration of Almario has considered siyokoy words to be improper and therefore its use discouraged.
[2] The proliferation of siyokoy words is fast due to its usage by celebrities, broadcasters, writers and academics who have limited knowledge in Spanish.
He also prefers Filipino speakers to straight up use English terminologies if they are not aware of the Spanish equivalent.
The most preferable approach is to use existing Filipino words such as larawan for "image".
