   We will check to see if what you have said is really the truth.

• Synonym案の定あんのじょうNeutralMeans 'sure enough', typically when something feared actually happens; unlike 「果たして」, it has no interrogative 'really/ever' use.
• SynonymやっぱりCasualThe colloquial form of 「矢張り」, very common in everyday speech. 「果たして」 leans written and can also be used in questions.
• Synonym果然かぜんWrittenA written word for 'sure enough', found mainly in prose; 「果たして」 is the more common choice.
• SynonymさてこそWrittenAn archaic word meaning 'just as I thought' or 'no wonder', with a classical literary flavor.
• RelatedやはりNeutralMeans 'as expected' or 'after all'; common in both speech and writing, with 「やっぱり」 as its more colloquial form. 「果たして」 leans written and can be interrogative.
• RelatedやっぱしCasualA loose, casual variant of 「やっぱり」 meaning 'as expected' — even more informal than 「やっぱり」 itself.

For questions asking 'really?/ever?' use 「果たして」; for everyday 'as expected' say 「やっぱり」. 「案の定」 suits a feared outcome, 「果然」 is written prose, 「さてこそ」 is archaic; 「やっぱし」 is a looser spoken variant of 「やっぱり」.
