hide particular category post from front page only [closed]

To exclude a category from the home page, use the pre_get_posts action:

function exclude_category( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) {
        $query->set( 'cat', '-1,-1347' );
    }
}
add_action( 'pre_get_posts', 'exclude_category' );

In this example, 1 and 1347 are the category IDs you’d like to exclude.

Also see the Conditional Tags page for a list of all the is_ conditionals you can use to target this function to different types of pages.
