Large Type Output
You can select Large Type as an output type for your Workflow.
Alfred will show your workflow's argument according to your Large Type Appearance Preferences; filling the screen or surrounded by a semi-transparent background.
Using Dynamic Placeholders
From Alfred 3.3, dynamic placeholders include more advanced clipboard and variable substitution, allowing you to include previous clipboard items or upstream workflow variables.
Take a look at the Dynamic Placeholders page for more details.
