The phrase translations with source-language phrase tagging are as follows:

• was — [was](javascript:void(0))
• ist — [ist](javascript:void(0))
• ads — "ads" is an English abbreviated form for "advertisements" used in German as well; it is not native script so no tag is applied. However, if referring to the German abbreviation ADS for Aufmerksamkeitsdefizit-Syndrom (Attention Deficit Syndrome), that would be tagged as [ADS](javascript:void(0)).

In summary:

• [was](javascript:void(0))
• [ist](javascript:void(0))
• ads (in English usage)
• [ADS](javascript:void(0)) (if referring to the German psychological term)

"Ads" commonly means advertising messages, while "ADS" in German refers to an attention deficit syndrome without hyperactivity, distinguished from ADHS (ADHD).
